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

             Summary: TxnHandler.enqueueLockWithRetry() should now write TXN_COMPONENTS if
partName=null and table is partitioned
                 Key: HIVE-17821
                 URL: https://issues.apache.org/jira/browse/HIVE-17821
             Project: Hive
          Issue Type: Bug
          Components: Transactions
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman
            Priority: Critical


LM may acquire read locks on the table when writing a partition.
There is no need to make an entry for the table if we know it's partitioned since any I/U/D
must affect a partition (or set of).

Pass isPartitioned() in LockComponent/LockRequest or look up in TxnHandler
