Subject Re: Apache cassandra not joining cluster ring
Date Thu, 17 Apr 2014 05:25:22 GMT
After explicitly enabling port
9160 (Cassandra client port (Thrift)) in that particular node it's
connected to ring however other nodes are working with same configuration.

Now Opscenter is installed in that particular node after explicitly enabling
61620 (OpsCenter monitoring port), 61621 (OpsCenter agent port) in all
nodes though in other nodes error is displaying while installing from GUI as

"Unable to find a java executable! Please install java or set JAVA_HOME.
Exit code: 4".

Though java is installed & JAVA_HOME is also set for all users.
$ echo $JAVA_HOME

/app/jdk1.6.0_16

Please help!
