[jira] Commented: (MAPREDUCE-1018) Document changes to the memory
management and scheduling model
[ https://issues.apache.org/jira/browse/MAPREDUCE-1018?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12873845#action_12873845 ]
Tom White commented on MAPREDUCE-1018:
--------------------------------------
Hemanth, This is going to conflict with MAPREDUCE-1404, which moves cluster setup and commands manual pages to common. Would you be able to stage this one to go in after MAPREDUCE-1404?
bq. One thing I've not included is the documentation on the RSS based monitoring introduced in MAPREDUCE-1221. I am not yet familiar with that part of the code. Also, this patch itself looks reasonably big. Hence, I would request for those changes to be incorporated as a follow-up, though they should be treated as a blocker for the 0.21 release as well. Thoughts ?
Fine to have as a separate issue, but I don't think it would stop a release going out (we could add it in a point release if it didn't make it into the .0 release).
