To whom it may concern,
I have a cluster with Ambari 22.214.171.124 on it and HDP 3.1.5. All the nodes in it are RHEL 7.9.
I saw here:
...someone posted instructions for updating Java on an older version of Ambari. It boils down to putting the same JDK in the same path on all of your nodes, then doing a couple of ambari-server commands.
Am I supposed to stop all of the individual applications (HDFS, YARN, ZooKeeper, etc.) before doing this, or does the 'ambari-server restart' on the Ambari server handle all that? Is there an updated procedure for Ambari 126.96.36.199?
Please respond when you can.
