Date Fri, 12 Dec 2014 01:58:13 GMT
Jian He created YARN-2952:
-----------------------------

             Summary: Incorrect version check in RMStateStore
                 Key: YARN-2952
                 URL: https://issues.apache.org/jira/browse/YARN-2952
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jian He


In RMStateStore#checkVersion:  if we modify  tCURRENT_VERSION_INFO to 2.0, it'll still store
the version as 1.0 which is incorrect; 
{code}
    // if there is no version info, treat it as 1.0;
    if (loadedVersion == null) {
      loadedVersion = Version.newInstance(1, 0);
    }
    if (loadedVersion.isCompatibleTo(getCurrentVersion())) {
      LOG.info("Storing RM state version info " + getCurrentVersion());
      storeVersion();
{code}
