Review request for hive, Ashutosh Chauhan and Gopal V.
Bugs: HIVE-23446
https://issues.apache.org/jira/browse/HIVE-23446
Repository: hive-git
Description
-------
Currently UGI pool is maintained at QueryInfo level. However, when short
queries and lots of AMs are there, it ends missing IPC connection cache. Too
many connections are are also established. Patch tries to avoid that by
maintaining this at ContainerRunner level. It retains the current behaviour of
having multiple connection to same AM (otherwise can get bottlenecked on single
connection)
Diffs (updated)
