Cassandra 3 will reach its end of life in 2023. Teamwork Cloud 2021x Refresh 2 Hot Fix 5 works with both Cassandra 3 and 4. Upgrades and new deployments should install Cassandra 4. Cassandra 3 should only be installed for data migration or recovery.

yum -y install java-1.8.0-openjdk

From the Java version list, please check that the recommended Oracle JVM version is compatible with the Teamwork Cloud version you are using. In order to consolidate all of the installed applications in a single location, we will be installing them under /opt/local/java. To facilitate deployment, you may deploy using the associated script (install_java_202.sh).  Oracle no longer allows direct download of their JDK, so it must be downloaded offline and placed in the same location as the install scripts. The installation script extracts it into the proper location, invokes the alternative command to point the system to this instance (you may need to select it when prompted), and creates entries in /etc/environment. Upon completing the installation, issue the following command:

java -version

You should receive output such as the following:

java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)

If properly installed, you will see Java identified as Java HotSpot(TM)
