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

             Summary: Bad enum in hbase:meta info:state column can fail loadMeta and stop startup
                 Key: HBASE-23117
                 URL: https://issues.apache.org/jira/browse/HBASE-23117
             Project: HBase
          Issue Type: Bug
    Affects Versions: 2.0.2
            Reporter: Michael Stack


Had a bad value in info:state field in meta and it made it so couldn't start up the cluster; loadMeta would not succeed. If a bad state, should note it, compensate, and move on.

The bad entry was an own goal that happened while trying to fix other issues in a pre-hbck2 cluster.

Here was the exception:
