Eugene Koifman updated HIVE-18693:
----------------------------------
Description:
TestTxnCommands2#writeBetweenWorkerAndCleaner with minor
changes (changing delete command to insert command) fails on MM table.
Specifically the last SELECT commands returns wrong results.
But this test works fine with full ACID table.
======
MM table inserts were not making entries into TXN_COMPONENTS, thus the
{{txnHandler.cleanEmptyAbortedTxns();}} logic in {{Initiator}} can wipe out
TXNS entry for an aborted transaction before the relevant files on disk are
removed.
