Subject [jira] [Created] (HIVE-16013) Fragments without locality can stack up on nodes
Date Wed, 22 Feb 2017 22:37:44 GMT
Prasanth Jayachandran created HIVE-16013:
--------------------------------------------

             Summary: Fragments without locality can stack up on nodes
                 Key: HIVE-16013
                 URL: https://issues.apache.org/jira/browse/HIVE-16013
             Project: Hive
          Issue Type: Bug
          Components: llap
    Affects Versions: 2.2.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran


When no locality information is provide, task requests can stack up on a node because of consistent
no selection. When locality information is not provided we should fallback to random selection
for better work distribution.
