Siddharth Seth updated HIVE-16655: ---------------------------------- Attachment: HIVE-16655.01.patch The patch. Relies on the start notifications from Tez, to detemine the state of a fragment, and preempt accordingly. cc [~prasanth_j], [~sershe] for review. Cannot submit to jenkins since the Tez patch introduces new APIs. > LLAP: Avoid preempting fragments before they enter the running state > -------------------------------------------------------------------- > > Key: HIVE-16655 > URL: https://issues.apache.org/jira/browse/HIVE-16655 > Project: Hive > Issue Type: Bug > Reporter: Siddharth Seth > Assignee: Siddharth Seth > Attachments: HIVE-16655.01.patch > > > Currently in the AM, fragments may be preempted as soon as they are > allocated, without knowing whether they will move into the RUNNING state or > not. Leads to a lot of unnecessary kills. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
