Hadoop: Cannot use Jps command

Question

The problem is

  hduser@saket-K53SM:/usr/local/hadoop$ jps
  The program \'jps\' can be found in the following packages:
  * openjdk-6-jdk
  * openjdk-7-jdk
         


        

Answer 1

This problem is caused since you have installed JDK from Oracle (may be). You can fix this problem by using update-alternatives program to link jps to standard path directory. Use this command to fix this in a terminal

 sudo update-alternatives --install /usr/bin/jps jps /usr/lib/jvm/jdk1.6/bin/jps 1

Use the actual jps program path in the appropriate jdk (your version of jdk) instead of jdk1.6 which is specific to me. Hope this will help.
