Mithun Radhakrishnan commented on HIVE-16820: --------------------------------------------- bq. MergeFileTask doesn't appear to implement shutdown at all. :] Ah, but doesn't it need one? It is conceivable that a user might cancel a query between the TezTask and the MergeFileTask, (or simply interrupt an {{ALTER TABLE CONCATENATE}}). In that case, the merge will run through to the end, in spite of cancellation. I wonder if there isn't value in applying the HIVE-12556 + HIVE-16820 treatment for MergeFileTask as well. > TezTask may not shut down correctly before submit > ------------------------------------------------- > > Key: HIVE-16820 > URL: https://issues.apache.org/jira/browse/HIVE-16820 > Project: Hive > Issue Type: Bug > Reporter: Visakh Nair > Assignee: Sergey Shelukhin > Fix For: 3.0.0 > > Attachments: HIVE-16820.01.patch, HIVE-16820.patch > > > The query will run and only fail at the very end when the driver checks its > own shutdown flag. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
