> If external tables are enabled for replication on an existing repl policy,
> then bootstrapping of external tables are combined with incremental dump.
> If incremental bootstrap load fails with non-retryable error for which user
> will have to manually drop all the external tables before trying with another
> bootstrap dump. For full bootstrap, to retry with different dump, we
> suggested user to drop the DB but in this case they need to manually drop all
> the external tables which is not so user friendly. So, need to handle it in
> Hive side as follows.
> REPL LOAD takes additional config (passed by user in WITH clause) that says,
> drop all the tables which are bootstrapped from previous dump.
> hive.repl.clean.tables.from.bootstrap=<previous_bootstrap_dump_dir>
> Hive will use this config only if the current dump is bootstrap dump or
> combined bootstrap in incremental dump.
> Caution to be taken by user that this config should not be passed if previous
> REPL LOAD (with bootstrap) was successful or any successful incremental
> dump+load happened after "previous_bootstrap_dump_dir".
