Review comment:
Shall we create the _external_info file only if
shouldDumpExternalTableLocation?

> 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.
