> as part of HIVE-17814 we are going to handle the issue w.r.t to hive as well as the post
execution hook api's . However for atlas which is a commonly used hive post execution hook,
we want to prevent additional memory usage. Also Atlas currently does not handle /  work on
replication queries hence overloading the hookContext with TaskRunner objects is just using
a lot of memory.  The same should be true for other execution hooks as well since replication
is a new functionality,
> This task is to reduce that for replication related queries.
