Date Mon, 10 Jul 2017 20:37:00 GMT
Ray Chiang created YARN-6798:
--------------------------------

             Summary: NM startup failure with old state store due to version mismatch
                 Key: YARN-6798
                 URL: https://issues.apache.org/jira/browse/YARN-6798
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 3.0.0-alpha4
            Reporter: Ray Chiang


YARN-6703 rolled back the state store version number for the RM from 2.0 to 1.4.

YARN-6127 bumped the version for the NM to 3.0

    private static final Version CURRENT_VERSION_INFO = Version.newInstance(3, 0);

YARN-5049 bumped the version for the NM to 2.0

    private static final Version CURRENT_VERSION_INFO = Version.newInstance(2, 0);

During an upgrade, all NMs died after upgrading a C6 cluster from alpha2 to alpha4.
