There are several options for installing a JDK on your CDP Private Cloud Base hosts:
  • Install OpenJDK 8 on the Cloudera Manager server host and then allow Cloudera Manager to install OpenJDK 8 on its managed hosts. This is the automatic option.
  • Manually install a supported JDK on all cluster hosts before installing Cloudera software.

Requirements:

  • The same version of the JDK must be installed on each cluster host.
