Subject [jira] [Commented] (MAPREDUCE-4275) Plugable process tree
Date Thu, 02 Aug 2012 17:48:04 GMT

    [ 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?
