    [ https://issues.apache.org/jira/browse/HADOOP-4287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12637421#action_12637421

Sreekanth Ramakrishnan commented on HADOOP-4287:
------------------------------------------------

The counter assignments from terminate method should remain, because only thing which we are
handling is prevention of updating the counters after the job has been terminated due to maximum
failures reached, as mentioned by Vinod above.
 
If we remove the assignment then value of running reduces would not fall back to zero, in
case a job which is terminated when it has 5 maps in total and has 2 running maps when it
is terminated. Then if we remove the assignment from terminate then the JIP.running task would
say 2 and waiting would always point to 3.

> This I observed while running a job that always fails because of reduce failures. Need
to investigate this.
