[jira] [Created] (HBASE-21864) add region state version and reinstate YouAreDead exception in region report

Sergey Shelukhin created HBASE-21864:
----------------------------------------

             Summary: add region state version and reinstate YouAreDead exception in region report
                 Key: HBASE-21864
                 URL: https://issues.apache.org/jira/browse/HBASE-21864
             Project: HBase
          Issue Type: Bug
            Reporter: Sergey Shelukhin


The state version will ensure we don't have network-related races  (e.g. the one I reported in some other bug - RS: "report {R1} ..." M: "close R1" R: "I closed R1" M ... "receive report {R1}" M: "you shouldn't have R1, die").
Then we can revert the change that removed YouAreDead exception... RS in incorrect state should be either brought into correct state or killed because it means some bug; right now of double assignment happens (I found 2 different cases just this week ;)) master lets RS with incorrect assignment keep it forever.
