Also, You can browse to this location which is the jdk root /usr/lib/jvm/jdk1.6.0_43/bin/ and if you can find jps (jdk1.6 comes with jps but not openjdk and its preferable to use sun jdk6 for hadoop) there simple type jps and execute which will give you all the java process in the JVM
Good handy jps command. You can add the following in the .bashrc file in the /home/<user>/ unalias jps $> /dev/null alias jps="/usr/lib/jvm/jdk1.6.0_43/bin/jps" and log out and login. So that you can use jps anywhere you dont have to open the jdk file location for executing jps.
