You will need to install the desired JDK to all your cluster hosts manually on some common location like

Example: )on every cluster host same path should exist

/usr/jdk64/jdk1.8.0_172

.

Now on the ambari server host run the following command to setup the JDK.

# ambari-server setup –j /usr/jdk64/jdk1.8.0_172
# ambari-server restart

.

Thanks @Jay Kumar SenSharma.

Question: On other nodes, do we have to do anything after installing new version of JAVA. Just by putting the JAVA in the same path as Ambari-server, is that going to be ok..?
