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

This might also be a reason. Its simple: See if $javac works. Note: $java might work, check javac. If $javac is not working then $jps will not work either. So you might want to do something like

export PATH=$PATH:$JAVA_HOME/bin

and try again. both javac and jps. good luck.
