> Since we run in to the possibility of creating a large number tasks during replication
bootstrap dump
> * we may not be able to hold all of them in memory for really large databases, which
might not hold true once we complete HIVE-16892
> * Also a compile time lock is taken such that only one query is run in this phase which
in replication bootstrap scenario is going to be a very long running task and hence moving
it to execution phase will limit the lock period in compile phase.
