I have followed the install instructions and gone over them multiple times with a fine comb and I am still unable to determine why I cannot resolve the NameService. I have the omniNames service running, but when I run omniEvents I get the following
omniEvents: [32190]: Warning - failed to resolve initial reference 'NameService'. Exception NO_RESOURCES
I receive this same error message when I attempt to connect within the Sandbox in the IDE, but I am still able to run components and connect them while running in the IDE Sandbox.
I ran nameclt list and received the following output
Cannot resolve the root context.
Have you set up the configuration file properly?
my config file contains the following
InetRef = NameService=corbaname::127.0.0.1
InetRef = EventService=corbaloc::127.0.0.1:11169/omniEvents
I have also verified that the services are being started on the correct ports using netstat.
What am i missing to get connected to the name service?
It appears that your error might be due to a typo in /etc/omniORB.cfg. In your example you use "InetRef" when it should be "InitRef".
Double check the settings and then restart omniNames and omniEvents and try nameclt again. If you get an error such as this:
$ nameclt list
Caught a TRANSIENT exception when trying to validate the type of the
NamingContext. Is the naming service running?
Double check that omniNames is indeed running (i.e. ps -ef | grep omniNames).

I am referring to the following link Installation Link for installing Kubernetes on Ubuntu 18.04. I am getting the following errors on typing the command :
sudo kubeadm join 192.168.0.114:6443 --token qgce4f.tgzda1zemqnro1em --discovery-token-ca-cert-hash sha256:6ebc15a5a9818481f8a98af01a7a367ba93b2180babb954940edd8178548773a ignore-preflight-errors=All

Can someone please tell me how to fix this? Thanks !
Consider using the kubeadm reset command as described here:
The "reset" command executes the following phases:
preflight Run reset pre-flight checks
update-cluster-status Remove this node from the ClusterStatus object.
remove-etcd-member Remove a local etcd member.
cleanup-node Run cleanup node.
The fourth phase of this command should fix the 4 errors you mentioned:
A ) It will stop the kubelet service - so port 10250 will be released.
B ) It will delete contents of the following directories:
/etc/kubernetes/manifests
/etc/kubernetes/pki
C ) It will delete the following files:
/etc/kubernetes/admin.conf
/etc/kubernetes/kubelet.conf
/etc/kubernetes/bootstrap-kubelet.conf
/etc/kubernetes/controller-manager.conf
/etc/kubernetes/scheduler.conf
(*) Make sure you run the kubeadm join command with verbosity level of 5 and above (by appending the --v=5 flag).
I am having issues with node-red and can no longer run any flows, i am not sure what to do anymore.
i get the following error
Imported unrecognised type: mqtt-env-broker
Flows stopped due to missing node types. Check logs for details.
Tried to remove this module from the palette but get the following error, i am also unable to disable it
Failed to remove: node-red-contrib-mqtt-env
Error: Type in use: mqtt-env-broker
Check the log for more information
I have installed the node-red-admin and tried to remove it from command line, so i issued the following command
sudo node-red-admin remove node-red-contrib-mqtt-env/mqtt-env
i get the following error
404: Cannot DELETE /nodes/node-red-contrib-mqtt-env/mqtt-env
this is what i get when i ran the following command
node-red-admin list
Nodes Types State
node-red-contrib-mqtt-env/mqtt-env mqtt-env in error
mqtt-env out
mqtt-env-broker
node-red-dashboard/ui_audio ui_audio enabled
...
...
node-red/mqtt mqtt in error
mqtt out
mqtt-broker
The flows are stopped because they are trying to use a node type you have not got installed - or in this instance, it appears, is hitting an error when it tries to start
The runtime won't let you remove the node because it is referenced in your flow.
To fix this you need to delete any of the nodes referenced by this module from your flow. The name mqtt-env-broker suggests it is a configuration node rather than a regular flow node. Open the Configuration Nodes sidebar panel (from the drop-down menu) and look for any unknown config nodes. Double click on them and delete them. Once you've removed them, hit deploy and things should start working again.
You should then be able to delete the node module from your runtime.
I've been at it for days but could not solve my problem.
I am running:
mpiexec -hostfile ~/machines -nolocal -pernode mkdir -p $dstpath where $dstpath points to current directory and "machines" is a file containing:
node01
node02
node03
node04
This is the error output:
Failed to parse XML input with the minimalistic parser. If it was not

--------------------------------------------------------------------------
ORTE was unable to reliably start one or more daemons.
This usually is caused by:
* not finding the required libraries and/or binaries on
one or more nodes. Please check your PATH and LD_LIBRARY_PATH
settings, or configure OMPI with --enable-orterun-prefix-by-default
* lack of authority to execute on one or more specified nodes.
Please verify your allocation and authorities.
* the inability to write startup files into /tmp (--tmpdir/orte_tmpdir_base).
Please check with your sys admin to determine the correct location to use.
* compilation of the orted with dynamic libraries when static are required
(e.g., on Cray). Please check your configure cmd line and consider using
one of the contrib/platform definitions for your system type.
* an inability to create a connection back to mpirun due to a
lack of common network interfaces and/or no route found between
them. Please check network connectivity (including firewalls
and network routing requirements).

I have 4 machines, node01 to node04. In order to log into these 4 nodes, I have to first log in to node00. I am trying to run some distributed graph functions. The graph software is installed in node01 and is supposed to be synchronised to the other nodes using mpiexec.
What I've done:
Made sure all passwordless login are setup, every machine can ssh to any other machine with no issues.
Have a hostfile in the home directory.
echo $PATH gives /home/myhome/bin:/home/myhome/.local/bin:/usr/include/openmpi:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
echo $LD_LIBRARY_PATH gives
/usr/lib/openmpi/lib
This has previously worked before, but it just suddenly started giving these errors. I got my administrator to install fresh machines but it still gave such errors. I've tried doing it one node at a time but it gave the same errors. I'm not entirely familiar with command line at all so please give me some suggestions. I've tried reinstalling OpenMPI from source and from sudo apt-get install openmpi-bin. I'm on Ubuntu 16.04 LTS.
You should focus on fixing:

I have two curls, one that comes with the OS, and another that comes with an application I installed. When I try run the one that comes with the application, I get "`curl: (2) Failed initialization", what is the problem here?
I am installing nutch2.2.1 on my centOS virtual machine and getting an error injecting the seed urls(directory name). I used this command:
/usr/share/apache-nutch-2.1/src/bin/nutch inject root/apache-nutch-2.1/src/testresources/testcrawl urls
And i got an error :
Error: Could not find or load main class org.apache.nutch.crawl.InjectorJob
Similarly, for the command
/usr/share/apache-nutch-2.1/src/bin/nutch readdb
gives me an error:
Error: Could not find or load main class org.apache.nutch.crawl.WebTableReader
What should i do to fix these errors?
I am following the tutorial from: http://wiki.apache.org/nutch/Nutch2Tutorial and followed the same steps as suggested.
Also my query also revolves around setting the path for ant. Every time i open a new session i have to set the ANT_HOME and PATH environment variable manually. And then they work all fine. Same is the case with setting JAVA_HOME.
You should go to $NUTCH_HOME/runtime/local/ directory to run the the commands.
