Manually Installing OpenJDK
Before installing Cloudera Manager and Runtime, perform the steps in this section to install OpenJDK on all hosts in your cluster(s).
OpenJDK 8 is the only supported OpenJDK version for CDP Data Center Edition.
Note that the path for the default truststore for OpenJDK 8 is
jre/lib/security/cacerts.
You must install a supported version of OpenJDK. If your deployment uses a version of OpenJDK lower than 1.8.0_181, see TLS Protocol Error with OpenJDK.
Log in to each host and run the command for the version of the JDK you want to
install:
- RHEL
-
OpenJDK
8
sudo yum install java-1.8.0-openjdk-devel
