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
correctly 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 exception in my code saying
"Exception in thread "main" java.lang.UnsupportedClassVersionError:
it/polimi/tssotn/dataloader/DataLoader : Unsupported major.minor 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?
