Followed the steps to install the apache-cassandra latest build. Upon first startup (./cassandra -f), I get this:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/cassandra/thrift/CassandraDaemon
Caused by: java.lang.ClassNotFoundException: org.apache.cassandra.thrift.CassandraDaemon

Could not find the main class: org.apache.cassandra.thrift.CassandraDaemon. Program will exit.
I exported the JAVA_HOME path, etc. What am I doing wrong? I should note that I am on an Ubuntu Lucid machine.
The first thing you should do is setup CASSANDRA_HOME path to the Cassandra root directory.
Try running cassandra cassandra -f and everything will run smooth. (Cassandra actually checks CASSANDRA_HOME environment variable to find the lib folder to run the deamon).
If using Ubuntu (Lucid), use the tutorial here: http://dustyreagan.com/installing-cassandra-on-ubuntu-linux/, which is based on the debian package. Building from Git didn't work.
This answer may help you if you don't technically need to build from source, and if you're just getting started with a fresh Cassandra install rather than upgrading an existing one.
I had the same problem when building from source. To get around it, I used a development build from the "Latest Builds (Hudson)" http://cassandra.apache.org/download/ link here.
The next problem you'll encounter is that no keyspaces will be set up on a fresh install. To get around that problem you can use the last release 0.6.3. That solution didn't work for me, because I wanted to use Pycassa which needs 0.7.
So what I had to do was the following steps:
Fire up a JMX console. Personally I'm not located with the server running Cassandra, so I needed to use ssh tunnels, like this:
jconsole -J-DsocksProxyHost=localhost -J-DsocksProxyPort=1080
Then used this funky looking url to connect:
service:jmx:rmi:///jndi/rmi://my.hostname.com:8080/jmxrmi
Then on the left side
expand org.apache.cassandra.service
expand Storage Service expand Operations
select loadSchemaFromYAML
at the top right, click the loadSchemaFromYAML button to invoke it.
You can use the same steps to add new keyspaces during development, once you figure out what you want your schema to look like. But the above steps only work if you have no data. So you would have to remove all your data using rm /var/lib/cassandra/* after taking down the server. (Of course, there are other steps you can take that are more complicated to migrate data without destroying it.)
I realize you didn't ask about creating keyspaces, but on a trunk version of cassandra, if your'e just getting started, that's the very next problem you'll have. I just spent a day solving it, and am hoping it helps.
Can you provide more details? Are you using ubuntu Open JDK 6?
Also, you don't have to build from source. Just get the binary from the following url:
http://mirror.nexcess.net/apache/cassandra/1.1.2/apache-cassandra-1.1.2-bin.tar.gz

I was in the middle of working on some minor code changes when all of a sudden I started getting the following error on startup:
A host error has occurred during startup operation '78d5d8fd-e81c-4707-87ca-6b801430fef1'.
[2021-01-08T13:02:40.279Z] System.IO.FileSystem: Could not find a part of the path 'C:\Users\schiefaw\AppData\Local\AzureFunctionsTools\Releases\3.17.0\workers'.
I looked at the path and found everything exists until I get to "workers".
I, of course, assumed it was something I did, so I backed out all changes to no effect. Then I uninstalled visual studio and all Azure products I could find and reinstalled to no effect. I created a new user (since the file it is looking for is in my user folder) to no effect.
I then created an entirely new instance of a windows virtual machine and installed the development environment to no effect (same error).
I am completely stuck on this. Does anyone have any ideas on what I can try next?
Thanks!
I think this is a bug from that 3.17 release. But here is a work-around: you can add the "workers" folder (empty folder) and it should work. Another way if you have a copy of the previous version (such as 3.16.x), you can copy the content to the 3.17.0 one.

You need to enable ansi control code processing. See here for details.
By Jason Karns in shell

Having used git on windows for over three years now, I’ve fallen back in love with the command line. Bash, of course, not the windows command prompt. Beautiful, ubiquitous, warty bash. Git depends heavily on GNU utilities so on Windows it requires either cygwin or msys. Having been burned by cygwin in the past, I prefer the minimalism and simplicity of msys + mingw. Along with git, the entire ruby ecosystem lives in the shell. However, the numerous tools, gems and utilities that assume standard ANSI color support in the shell began to wear on me. Lo and behold, there is a lovely solution to provide ansi color support for bash (and cmd) on Windows: ansicon.
Download the zip and extract. There are a few ways to install:
Extract to a permanent location (I use C:/bin/ansicon). Execute ansicon.exe -i from within the appropriate directory for your system (x86/x64), and you’re all set. Any new shells (bash and windows cmd included) will autorun the ansicon utility for displaying color output. Be sure not to move the executable prior to running ansicon.exe –u. This removes the registry entry and prevents an ugly error message for every command shell.
Alternatively, place the ansicon executable in your PATH, or add its location to your PATH. Then you can launch ansicon for a session with ansicon.exe –p.
This utility has been working great for my on Windows XP. I’ve been having trouble getting it to work on Windows 7, but I hear it should be supported. I’ll post an update when the Windows 7 issue is resolved.
Update
Root cause, uncovered! If you use JRuby with a 64-bit JVM on Windows x64, ansicon won’t work. The issue is that ansicon (64-bit) is capable of injecting into 32-bit processes, but not vice versa. Currently, the JRuby launcher is a 32-bit executable. Thus, if you’re running a 64-bit shell (cmd, bash, or otherwise), ansicon will inject correctly into that process. It will then inject successfully into the 32-bit JRuby launcher process. At this point, for all intents and purposes, you’re running the 32-bit version of ansicon. Thus, if you’re running JRuby on a 64-bit JVM, then 32-bit ansicon is not able to inject into 64-bit JVM. There is an open feature request for JRuby to ship its 64-bit version with a 64-bit launcher. You should vote for this feature. I also hear that adoxa (Jason Hood) has a potential fix for this issue in the works. Stay posted.
Of course, the easiest solution at the moment is to ensure that JRuby uses a 32-bit JVM. Just change (or set) your JAVA_HOME environment variable to point to a 32-bit JVM and you’re golden.
Update 2: Issue Resolved
The latest 64-bit binaries (ansi6432.zip) have fixed the issue. Just download and extract them over-top the 1.51 version.
For MingGW64 I found going into the Options > Terminal and switching from xterm (the default I presume) to xterm-256color fixed the issue. I also restarted the console.
This answer helped me with my weird characters in gradle output from git bash in windows. Just add export TERM=cygwin to the last line of git/etc/bash.bashrc. If this helps you, be sure to send the upvotes to their answer—I'm only reposting it here since this is where google brought me.
I didn't remember the last version of GIT. I faced same problem after updating Git Bash to 2.11.
Downgrading to 2.10 solved my problem.

I am currently trying to automate the process of bamboo remote agent installation and uninstallation. I have run into a problem in regards to adding and removing capabilities.
What I am trying to automate:
(The following is what I do on the bamboo server via the GUI, I want to do this on the remote agent machine via bash script.)
I install the remote agent on a VM machine, then start it up. I go to the bamboo interface and click on the newly created agent's name.
I add a custom capability type, for the key I put 'buildserver' and for the value I put the name of the agent.
I add an 'Executable' capability of type 'Command' with Executable label 'cygwin' and path 'C:\cygwin64\bin\bash'
I navigate to the git executable, and remove it by clicking 'delete.' <--- (the problem step)
what I've done.
I have looked here and found a way to automate steps 1-3 using the following "bamboo-capabilities.properties" file:
buildserver="AGENTNAME"
system.builder.command.cygwin="C:\cygwin64\bin\bash"
However I am stuck on how I would remove the git capability (step 4.) I've tried something appending something like this to the file:
system.git.executable=""
but it does not seem to do anything. Does anyone know how I would do this? There seems to be very little documentation about this online.
Thanks very much.
I never found a way to get around this, but I found a workaround. I later learned the point of removing git in my situation was to allow a shared capability that was also called git to take precedence. My workaround was to set the non-shared capability to the value of the shared capability. I am not 100% sure that this does the same thing, and I am not in a position to test it yet, but as a capability seems to be only a key-value pair I don't see why it wouldn't.... will update if anything breaks.
I am not sure if this is a JSF issue or a NetBeans issue. I am very new to both. I am also not sure if stackoverflow is the best SE site for this, so if I am wrong please help me out and migrate it. Thanks.
I have a project in a folder, let's say C:\Folder1, and when I try to "deploy" it on the GlassFish server, I get strange errors about a missing class... though that class is not even a part of this project. I believe that C:\Folder1 may have been something I used in the past for a different project but that is long gone. So this new project, if I move it to folder C:\Folder1a or C:\Folder2 or ANYTHING else but C:\Folder1... then it will deploy fine. But if I move it back to Folder1 (i.e. the exact same directory structure underneath that level), I get the mysterious error messages from GlassFish server about being unable to find the class that it doesn't even need.
I got a suggestion elsewhere to try "cleaning" and re-building the project, but that did not work. Here is more detail about the steps I followed.
Create new project in Netbeans, point it to an empty folder called Ex2605. After that, I bring a couple source files (.java and .xhtml) into that Ex2605 directory structure. When I clean and build, it says ok. When I try to deploy, I get this error:
Error occurred during deployment: Exception while loading the app :
java.lang.IllegalStateException: ContainerBase.addChild: start:
org.apache.catalina.LifecycleException: java.lang.RuntimeException:
java.lang.NoClassDefFoundError: LShoppingCart;. Please see server.log
for more details. C:\\Ex2605\nbproject\build-impl.xml:721: The
module has not been deployed. See the server log for details. BUILD
FAILED (total time: 16 seconds)
"ShoppingCart" is a class from a different project, that I once long ago had in a directory named Ex2605 at the same location. But that directory is long gone, it has been removed from the Netbeans project list, and there are NO references to the ShoppingCart class anywhere in any of the files currently in the Ex2605 folder. So that fact that Netbeans apparently is looking for something called LShoppingCart tells me it maintains a history somewhere else of what I used to have in the Ex2605 folder, and apparently I need to purge that history but have no idea how.
If I try all of the above with any directory NOT named Ex2605, it works fine.
Any ideas? Obviously I can work around it, but it still irks me.
Netbeans has a compile cache that sometimes causes problems. You could delete the compile cache and see if it helps.
Here are the steps from the answer to my question:
Stop the server
Clean the project
Stop NetBeans
Delete %HOME%.netbeans\6.9\var\cache
Start NetBeans
I am working on a maven project to build a simple utility api. The same source code when build on my office win XP machine, was successful. Now i am at home and working with same source code on CentOS machine. Here the build process failed strangely. The error it reports is ideally in my points should we warning message. As shown below.
[ERROR] com.vsd.Provider:[12,240] The import java.util.Set is never used
Can you please give me some idea, where can I look into?
It's hard to say without seeing your POM but the error reported looks like a violation of the Checkstyle rule UnusedImports (or something equivalent). Maybe this verification is triggered because of a setting defined in a profile that is not activated on your CentOS machine (as I said, hard to say). Anyway, to fix it, remove the unused import.
The problem was with the plug in being used to compile, It was a bug a shown below.
