anishek updated HIVE-17815:
---------------------------
Description:
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.
