So that, afterwards, scratch directory is left there in > hdfs. HDFS name node doesn't know it and try to do lease recovery. while such > instances happen more, it will eventually crash namenode. > The fix is to leverage hdfs clean up functionality. While creating scratch > dirs, hive registers it to hdfs cleanup hook. While killing happens, hdfs > will clean them up. -- This message is automatically generated by JIRA.
