    Description

      Currently as per the following code since the VERSION is marked as 2 .

      161	  protected static final Version CURRENT_VERSION_INFO = Version
162	      .newInstance(2, 0);

      RMStateStore#checkVersion will fail and RM will not be able to start with old state store. We can keep the version as 1.3 itself
