[jira] Updated: (HIVE-1655) Adding consistency check at jobClose() when committing dynamic partitions
[ https://issues.apache.org/jira/browse/HIVE-1655?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Namit Jain updated HIVE-1655: - Status: Resolved (was: Patch Available) Hadoop Flags: [Reviewed] Fix Version/s: 0.7.0 Resolution: Fixed committed. Thanks Ning Adding consistency check at jobClose() when committing dynamic partitions - Key: HIVE-1655 URL: https://issues.apache.org/jira/browse/HIVE-1655 Project: Hadoop Hive Issue Type: Improvement Reporter: Ning Zhang Assignee: Ning Zhang Fix For: 0.7.0 Attachments: HIVE-1655.patch In case of dynamic partition insert, FileSinkOperator generated a directory for a new partition and the files in the directory is named with '_tmp*'. When a task succeed, the file is renamed to remove the _tmp, which essentially implement the commit semantics. A lot of exceptions could happen (process got killed, machine dies etc.) could left the _tmp files exist in the DP directory. These _tmp files should be deleted (rolled back) at successful jobClose(). After the deletion, we should also delete any empty directories. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
