Does anyone know if Cassandra 2.2.3 supports Oracle Java 8? Is there a place where we can go to see supported Java versions?
I am not aware of a table or location that lists a cross-reference of all Cassandra versions and the Java versions that they support. But the Cassandra 2.2 installation documentation has this information:
Prerequisites
Latest version of Oracle Java Platform, Standard Edition 8 (JDK) or OpenJDK 7.
That can change with the version of Cassandra that you are installing. The Cassandra 2.1 installation doc also adds:
Note: It is recommended to use the latest version of Oracle Java 8 on all nodes. (Oracle Java 7 is also supported.)

what would be the compatible weblogic versions for the log-2.17.1. any Reference link is useful.
part of my research nowhere i found related solutions in the official sites
It would be more the java version that weblogic runs on. If it supports java 8 then you would be able to use log4j 2.17.1. I think weblogic 12.1.3 onwards supports java 8.
What version of CQL is CQLv4? Looking at the product compatibility page of the documentation shows versions 3.4, 3.3, 3.2... etc. Does the v4 in CQLv4 stand for 3.4?
I'm trying to find which versions of Cassandra are compatible with CQLv4.
https://docs.datastax.com/en/landing_page/doc/landing_page/compatibility.html?scroll=compatibilityDocument__cql-versions
I think that this table could do a better job for you. Protocol version 4 starts with Cassandra 2.2, and continues to version 3.x
As I have checked Scylla DB documentation and not found clearly where we can upgrade directly from Scylla version 2.1.x to 3.x.x directly.Is there any middle version upgrade required between 2.1.x to 3.x.x? Please help
The process is not documented, because it was not tested
You can follow the 2.1 to 2.2 instructions using 3.0, and everything should work, but the safest path will be 2.1 --> 2.2 --> 2.3 --> 3.0.2

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 planning to install my j2EE, spring rest based application on Red Hat Enterprise Linux 6.1. I want to know about the software version which is compatible. I am not sure whether all the new versions are compatible in REL 6.1.
The list of software's I need to install are
J2EE
Apache Tomcat
SpringRest
MySQL
The RHEL 6.1 can easily be updated for the latest versions of Java, Tomcat. For the latest MySQL, if there are dependencies not present in RHEL 6.1 then you could try either adding or updating them (using yum or building from source).
J2EE: Download from Oracle Java SDK download page [I believe you want JDK since the J2EE dependencies would be provided by Tomcat such as Servlet etc]
Apache Tomcat: Download the binaries from the tomcat apache website [http://tomcat.apache.org/]. That should be enough to get you started. If later on you would like to use openssl or apache portable runtime then that is easily setup as well. The tomcat documentation has useful documentation to set it up.
SpringRest: I believe you are referring to the java archives for it. You can use Maven to download the necessary dependencies or use Spring Boot (https://spring.io/guides/gs/rest-service/) or search Google for the many examples of bundling Spring dependencies with your application.
For MySQL: refer to http://dev.mysql.com/doc/mysql-repo-excerpt/5.6/en/linux-installation-yum-repo.html
