Phabricator updated HIVE-4000:
------------------------------
Attachment: HIVE-4000.D8493.1.patch
omalley requested code review of "HIVE-4000 [jira] Hive client goes into
infinite loop at 100% cpu".
Reviewers: JIRA
HIVE-4000 fix race condition in HashMap on Hive client
The Hive client starts multiple threads to track the progress of the MapReduce
jobs. Unfortunately those threads access several static HashMaps that are not
protected by locks. When the HashMaps are modified, they sometimes cause race
conditions that lead to the client threads getting stuck in infinite loops.
TEST PLAN
Test in the cluster with the query that was demonstrating the problem.
