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
 Try: sudo apt-get install <selected package>

My configuration is 

hduser@saket-K53SM:/usr/local/hadoop$ java -version
java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03, mixed mode)

set up conf/hadoop-env.sh

hduser@saket-K53SM:/usr/local/hadoop$ cat conf/hadoop-env.sh | grep JAVA_HOME
# The only required environment variable is JAVA_HOME.  All others are
# set JAVA_HOME in this file, so that it is correctly defined on
export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_33/

I know there is a question (http://stackoverflow.com/questions/7843422/hadoop-jps-can-not-find-java-installed) similar to this one. But i have installed Sun jdk here. So any help would be appreciated..

hadoop java

Use this command if you cannot use jps

ps -aux | grep java | awk '{print $12}'

It will show files as:

on CentOS7, I fixed that problem when I installed java-devel

# yum install java-1.8.0-openjdk-devel.x86_64
