[jira] [Commented] (MAPREDUCE-4275) Plugable process tree

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13427483#comment-13427483 ] 

Bikas Saha commented on MAPREDUCE-4275:
---------------------------------------

I am ok with the null pointer check. You are right that there should be a single factory getting OS specific resource objects. How about moving the procfsbasedprocesstree factory to resourcecalculatorprocesstree for now so that the code flow stays similar to what it currently is. Looks like you have some ideas for re-organizing this part of the code better. we could handle the factory creation and other refactorings etc as part of that change. sounds like a plan?
