--------------------------------------------------------------

A nit,  space after "," in log message would be required to pass the style check.

I think this can be logged at INFO level.

> Often time we see that ReplDumpTask waiting for hive.repl.bootstrap.dump.open.txn.timeout  (1h) to kill open txns and make progress, the only way to know for what txns it is waiting on is query the Metastore DB and backtrack the txns in HS2 logs to know if open txns are genuinely open for this long or any other issue.
> I am adding the debug log to print these txns which can help in debugging such issues.
