I set up a hbase/hadoop cluster on ec2 using Apache Whirr but when I ssh into the namenode (hbase master) and run $JAVA_HOME/bin/jps all I see running is jps, no mention of hbase or namenode. They are running, however, because I was able to work with both of them. Any explanation for this?

Answer 1

jps displays java processes for the current user, and sometimes only sessions it can resolve to the current user (so doesn't always work as expected).

Try a ps axww | grep java instead, that should list the java executables running, with full command line arguments
