It will be useful for Hadoop admin to save Hadoop cluster > resource by preventing users from submitting big mapreduce jobs. A mapredeuce > job with too many mappers may fail with OOM after running for long time. It > will be a big waste. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
