Hadoop How to use Jps command with Sun JDK installed

Question

The problem is

  hduser@user:/usr/local/hadoop$ jps
  The program 'jps' can be found in the following packages:
  * openjdk-6-jdk
  * openjdk-7-jdk
 Try: sudo apt-get install <selected package>

But I have Sun JDK and cant install it like this. What are other ways to use jps?

Answer 1

You can put JPS into your path or create an alias. The JPS executable can be found under $JAVA_HOME/bin/jps.

The alias for example could be:

alias jps='/usr/lib/jvm/jdk1.6.0_33/bin/jps'

Alternate for JPS, you can use ps with grep:

ps aux | grep java
