#Open jdk 6 install
You must install a supported version of OpenJDK. See Supported JDKs for information on which JDK versions are supported for Cloudera Enterprise releases. Important: When you install Cloudera Enterprise, Cloudera Manager includes an option to install Oracle JDK. See the following blog post for general information about migrating to Java 11: All You.The path for the default truststore has changed from (OpenJDK 8) jre/lib/security/cacerts to (OpenJDK 11) lib/security/cacerts.The package names used when installing the OpenJDK 11 and OpenJDK 8 are different and are noted in the steps below.OpenJDK 11 is supported as of Cloudera Manager and CDH 6.3. If you do not delete these files, Cloudera Manager and other components mayĬontinue to use the old version of the JDK. Delete the files from your previous Java installation.When All services successfully started appears, the task is complete and you can close the Command Details window. TheĬommand Details window shows the progress of stopping services. If you have enabled high availabilityįor HDFS, you can choose Rolling Restart instead to minimize cluster downtime. Click Restart that appears in the next screen to confirm.

You must also ensure that the Java Truststores are retained during the upgrade. JDK 1.8.0_162 enables unlimited strength encryption by default. (In a Cloudera Manager deployment, you automatically install the policy files for unmanaged deployments, install them manually.)
