Gopal V commented on HIVE-19124:
--------------------------------
You need to modify the TxnUtils to accept a ValidReaderWriteIdList and rewrite
the current impl as
{code}
return
createValidCompactWriteIdList(createValidReaderWriteIdList(tableWriteIds));
{code}
And then you don't need a new metastore object.
ValidReaderWriteIdList & ValidCompactorWriteIdList extends
ValidReaderWriteIdList
You need a ValidReaderWriteIdList.get to pass into compactionWriteIds.
> implement a basic major compactor for MM tables
