Hadoop : JPS can not find Java installed

Question

my configurations are

hduser@worker1:/usr/local/hadoop/conf$ jps
The program \'jps\' can be found in the following packages:
 * openjdk-6-jdk
 * openjdk-7-jd         


        

Answer 1

I would like to update topic for those who would face the same problem.

JDK8 also does not have the "jps" command but JDK7 does have it.
