---------------------------------

             Summary: Handle old data format while recovering RM
                 Key: YARN-5594
                 URL: https://issues.apache.org/jira/browse/YARN-5594
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.7.0
            Reporter: Tatyana But


We've got that error after upgrade cluster from v.2.5.1 to 2.7.0.

The reason of this problem is that we use different formats of files /var/mapr/cluster/yarn/rm/system/FSRMStateRoot/RMDTSecretManagerRoot/RMDelegationToken*
in these hadoop versions.

This fix handle old data format during RM recover if InvalidProtocolBufferException occures.
