What is the URL to download the source code for DataStax Community Edition??
I've been plowing through planetcassandra.org, DataStax website, and google without success. Have the Cassandra source off the Apache site...looking for the corresponding source for the DataStax community release.
Thanks!
The community distribution contains the corresponding Apache Cassandra release, and a free-but-not-open-source version of OpsCenter.

Can anyone tell me why is the gp_dump utility is not available with greenplum database by default? If I have to use it then what is the source to download and way to enable it? I have gone through a lot of online resources but nothing relevant could be found
Are you using Greenplum v6.x?
The latest version of gpbackup is located here:
https://github.com/greenplum-db/gpbackup/releases
and if interested, the corresponding s3 plugin here:
https://github.com/greenplum-db/gpbackup-s3-plugin
gp_dump is a very old, deprecated backup utility for Greenplum.
The older python based gpcrondump/gpdbrestore utilities are still bundled in Greenplum 4.3.x and 5.x versions, but do not support Greenplum 6.x and thus removed.
The newer Golang based gpbackup/gprestore utilities support Greenplum 4.3.22 and later, Greenplum 5.5 and later and Greenplum 6.0 and later all in the same binary.
Let me know if you have additional questions.

Try using pg_dump since Greenplum is a fork of postgres.
I am planning to execute spark from KNIME analytics platform. For this I need to install KNIME spark executors in the KNIME analytics platform.
Can any one please let me know how to install KNIME spark executors in the KNIME analytics platform for hadoop distribution CDH 5.10.X.
I am referring the installation guide from the below link:
https://www.knime.org/knime-spark-executor
I could successfully configure/integrate spark in KNIME.
I did it in CDH 5.7.
I followed the following steps:
1.Downloaded knime-full_3.3.2.linux.gtk.x86_64.tar.gz.
2.Exract the above mentioned pacakge and run installation for KNIME.
3.After KNIME is installed goto File ->Install KNIME Extensions -> Install Bigdata extensions(Check all the Spark related extensions and proceed).
Follow this link:
https://tech.knime.org/installation-instructions#download
4.Till now only the Bigdata related extensions have been installed but they need license to be functional.
5.License needs to be purchased.However,free trail for 30 days can be availed after which it needs to be purchased.
Folow this link :
https://www.knime.org/knime-spark-executor
6.After plugins are installed we need to configure Spark-job-server.
For that we need to download the compatible version of spark-job-server for the hadoop version we have.
Folow this link for version of spark-job-server and its compatible version :
https://www.knime.org/knime-spark-executor
I'm pretty sure it's as easy as registering for the free trial (and buying the license for longer than 30 days) and then installing the software from the Help->Install New Software menu.
As of version KNIME 3.6 (latest), it should be possible to connect to Spark via Livy, no specific executor deployment on a KNIME Server. Still in preview, but it should do it.

I have Datastax Community 3.0.4 installed on Windws 8.1 and I am trying to use Datastax Studio 1.0.2. The question is that I use authentication in Cassandra and therefore I need to authenticate also in Datastax Studio.
How can I solve it? How can I authenticate in Datastax Studio?
Studio and Community Edition are not meant to work together.
DataStax Studio is meant for use with DataStax Enterprise (in particular, for use exploring graph data in DSE). The Community edition you have installed only contains a distribution of Apache Cassandra (+ OpsCenter) and not DataStax Enterprise. So if you want to use DataStax Studio, you're going to have to get a copy of DataStax Enterprise first.
Since you're on Windows (and not on Windows 10), your options are a little limited. DSE doesn't run on Windows natively, so you'll have to use a Virtual Machine of some kind. There is a Sandbox image available from the DataStax Academy downloads page for both VirtualBox or VMWare, or you can always create your own VM (running Ubuntu or the Linux flavor of your choice) and Install DSE yourself.
Good luck!
I am very new to DBeaver. From forum i got to know that driver need to update for cassandra 3+ to work with DBeaver.
https://github.com/serge-rider/dbeaver/issues/167
I downloaded this new driver but unable to set the class path. Can anyone help me on this.Below is the current config i did for driver and cassandra.
As I had some problems finding Cassandra driver after DBeaver install, I went through another way:
Cloned this GitHub project
Built the jar file (mvn package)
Added this jar file to the Driver Manager configuration, using the JDBC Class Name and JDBC URL values as described at project README:
Download and use dbeaver enterprise edition (for free as well, not open source though) which includes cassandra driver by default.
Tested on DBeaver Community Edition 7.3.0.202011292131
Go to https://downloads.datastax.com/#odbc-jdbc-drivers
Select Simba JDBC Driver for Apache Cassandra
Open DBeaver
Database > Driver Manager
New
6. Do not fill Class Name manually, after Add file click Find Class and select.
Here is another solution you can use trial drivers and way to configure:

How can I upgrade the cassandra version and thrift version in Brisk?
Is there any tutorials kind of stuffs avalailble? I changed the build.properties file but on build, the version I mentioned couldn't be located at any repository.
Im trying to upgrade because of Cassandra Insertion Error
this issue im facing. I hope the comment mentioned there helps
What is the latest version of cassandra that brisk supports?
In support forums I see people mentioning, replace the jars. I don't understand where should I do that.
Thanks for Help in advance
Regards,
Tamil
Finally I found the way to upgrade Brisk's cassandra version.
I Downloaded apache-cassandra-0.8.6-bin from apache site.
Copied
lib/apache-cassandra-0.8.6.jar and lib/apache-cassandra-thrift-0.8.6.jar
to
brisk-1.0~beta2-bin/resources/cassandra/lib/
and removed the older version's cassandra and thrift jars
and just restarted brisk with ./brisk cassandra
and tried this
$ ./nodetool -h x.x.x.x version
ReleaseVersion: 0.8.6
So, I hope there won't any compatability issues, since in a forum a brisk dev mentioned tat brisk core works independently against cassandra core. But I'm yet to know the way to do it by building from src rather replacing jars in bin

Tamil
