Vinayakumar B reassigned HDFS-12120: ------------------------------------ Assignee: Vinayakumar B > Use new block for pre-RollingUpgrade files` append requests > ----------------------------------------------------------- > > Key: HDFS-12120 > URL: https://issues.apache.org/jira/browse/HDFS-12120 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Vinayakumar B > Assignee: Vinayakumar B > > After the RollingUpgrade prepare, append on pre-RU files will re-open the > same last block and makes changes to it (appending extra data, changing > genstamp etc). > These changes to the block will not be tracked in Datanodes (either in trash > or via hardlinks) > This creates problem if RollingUpgrade.Rollback is called. > Since block state and size both changed, after rollback block will be marked > corrupted. > To avoid this, first time append on pre-RU files can be forced to write to > new block itself. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
