Gunther Hagleitner updated HIVE-8760:
-------------------------------------
Attachment: HIVE-8760.2.patch
I'd like to propose a different change with smaller scope to get at least into
hive .14. I think that'd be safer for 2 reasons:
- It only changes ATSHook, anyone else will not see a change to their hooks
- It's faster if you run w/o ATSHook, because the clone only happens there.
Cloning is fairly expensive.
- It's a workaround for a hadoop issue. We should still try to get the hadoop
problem fixed and take it back out for perf reasons. That limits the changes to
only ATSHook again
Note: ExecHooks and hadoop conf have been around unchanged for quite a while so
leaving the code path alone as much as possible for .14 seems a safe choice.
