Gergo Repas created MAPREDUCE-6984: -------------------------------------- Summary: MR AM to clean up temporary files from previous attempt Key: MAPREDUCE-6984 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6984 Project: Hadoop Map/Reduce Issue Type: Improvement Components: applicationmaster Affects Versions: 3.0.0-beta1 Reporter: Gergo Repas
When the MR AM restarts, the {outputDir}/_temporary/{appAttemptNumber} directory remains on HDFS, even though this directory is not used during the next attempt if the restart has been done without recovery. So if recovery is not used for the AM restart, then the deletion of this directory can be done earlier (at the start of the next attempt). The benefit is that more free HDFS space is available for the next attempt. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-dev-h...@hadoop.apache.org
