Alan Gates commented on HIVE-10632:
-----------------------------------
TxnHandler.cleanupRecords For the first argument, enums or at least final
statics are better than magic characters.
TxnUtils.isAcidTable, I don't think we need to check beyond whether a table is
marked transactional. If it's marked as transactional let's just take that as
the truth and throw an error if we discover some other issue like it's not
bucketed or whatever.
Other than that, looks good.
> Make sure TXN_COMPONENTS gets cleaned up if table is dropped before
> compaction.

> The compaction process will clean up entries in TXNS,
> COMPLETED_TXN_COMPONENTS, TXN_COMPONENTS. If the table/partition is dropped
> before compaction is complete there will be data left in these tables. Need
> to investigate if there are other situations where this may happen and
> address it.
