[jira] Commented: (HADOOP-5908) ArithmeticException in heartbeats with zero map jobs

    [ https://issues.apache.org/jira/browse/HADOOP-5908?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712702#action_12712702 ] 

Vinod K V commented on HADOOP-5908:
-----------------------------------

This situation occurs if scheduler is invoked and it calls job.obtainNewMapTask() while the job-clean-up task of this job is still running. Discussed with this Devaraj who concurs that obtainNewMapTask()/obtainNewReduceTask() should return immediately, doing nothing, when job-cleanup is running.
