anishek commented on HIVE-17815:
--------------------------------

This will also mean that LineageLogger postexecution hook will not be able to log replication queries job ids.

> 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. 
> This task is to reduce that for replication related queries.
