NoClassDefFoundError: org/apache/hadoop/hbase/rest/Main

[Sharma, Avani]

I am trying to start and stop stargate rest server. I get 
ClassNotFoundException intermittently.
I did perform these steps :
  Place the Stargate jar in either the HBase installation root directory or 
lib/ directories.
  Copy the jars from contrib/stargate/lib/ into the lib/ directory of the 
HBase installation.
