Subject [jira] [Updated] (YARN-223) Change processTree interface to work better with native code
Date Thu, 03 Jan 2013 02:02:13 GMT

     [ https://issues.apache.org/jira/browse/YARN-223?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Nauroth updated YARN-223:
-------------------------------

    Attachment: YARN-223-branch-trunk-win.1.patch

branch-trunk-win diverged slightly due to committing YARN-234 ahead of this.  We have a merge
conflict now when trying to merge trunk to branch-trunk-win.  I am attaching a separate patch
for branch-trunk-win to resolve the merge conflict.

> Problem is that on every update of processTree new object is required. This is undesired
when working with processTree implementation in native code.
> replace ProcessTree.getProcessTree() with updateProcessTree(). No new object allocation
is needed and it simplify application code a bit.
