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!
