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

             Summary: Does ExIm work?
                 Key: HIVE-17657
                 URL: https://issues.apache.org/jira/browse/HIVE-17657
             Project: Hive
          Issue Type: Sub-task
          Components: Transactions
            Reporter: Eugene Koifman


there is mm_exim.q but it's not clear from the tests what file structure it creates 
On import the txnids in the directory names would have to be remapped if importing to a different
cluster.  Perhaps export can be smart and export highest base_x and accretive deltas (minus
aborted ones).  Then import can ...?  It would have to remap txn ids from the archive to new
txn ids.  This would then mean that import is made up of several transactions rather than
1 atomic op.  (all locks must belong to a transaction)
