    [ https://issues.apache.org/jira/browse/MAPREDUCE-1100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12859293#action_12859293

Vinod K V commented on MAPREDUCE-1100:
--------------------------------------

I opened MAPREDUCE-1716 to implement the second part of the algorithm I made [here|https://issues.apache.org/jira/browse/MAPREDUCE-1100?focusedCommentId=12772468&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12772468]
in this same JIRA issue. The first part related to retiring old logs is already handled by
MAPREDUCE-927.

can kick in.
