Running "ambari-server setup" should not disturb your running = cluster or cluster configuration by re-running setup. When prompted, modify= the JDK choice and then do not modify anything else.


A couple other notes...


1) Be sure the Custom JDK path is correct on all hosts in the cluster.

2) From Ambari Web, restart your services for the new JDK path to start = being used.

3) After you run setup, you can check the java.home property from the Am= bari Server...

Thanks for your reply, 
as I understood running ambari-server setup and selecting the jdk (or = using the -j argument as shown in the guide https://ambari.apache.org/1.2.2/installing-hadoop-using-ambari/content/amba= ri-chap2-2-1.html) will reset my current ambari installation so I will = loose th configuration of the cluster that is alread running. 
Is this correct? If so I can not re-run the setup otherwise I'll have = to reconfigure the entire cluster. 
Thanks.

Hi, 
I'm trying to upgrade the version of Java used in the cluster in order= to support Java 8. I've managed to install Java 8 and set the JAVA_HOME co= rrectly on all the nodes on the cluster. I've restarted the services using = ambari and even restarted the ambari server and agents but still wehn i subit a job using yarn i get an excepti= on in my code saying 
"Exception in thread "main" java.lang.UnsupportedClassV= ersionError: it/polimi/tssotn/dataloader/DataLoader : Unsupported major.min= or version 52.0" 
that basically means it is not running with Java 8. 
Is there a way to tell ambari to confgure yarn (and all other services= ) so use the new jre?
