current txn in which dump runs.
- // This is needed to ensure that Repl dump doesn't copy any data files
written by any open txns
- // mainly for streaming ingest case where one delta file shall have data
from committed/aborted/open txns.
- // It may also have data inconsistency if the on-going txns doesn't have
corresponding open/write
- // events captured which means, catch-up incremental phase won't be able
to replicate those txns.
- // So, the logic is to wait for configured amount of time to see if all
open txns < current txn is
- // getting aborted/committed. If not, then we forcefully abort those txns
just like AcidHouseKeeperService.

Review comment:
As discussed earlier, validTxnList need not be obtained from caller. Also,
shall return String itself.

> If ACID/MM tables to be enabled (hive.repl.dump.include.acid.tables) on an
> existing repl policy, then need to combine bootstrap dump of these tables
> along with the ongoing incremental dump.
> Shall add a one time config "hive.repl.bootstrap.acid.tables" to include
> bootstrap in the given dump.
> The support for hive.repl.bootstrap.cleanup.type for ACID tables to clean-up
> partially bootstrapped tables in case of retry is already in place, thanks to
> the work done during external tables. Need to test that it actually works.
