Subject [jira] [Created] (YARN-7162) Remove XML excludes file format
Date Tue, 05 Sep 2017 23:29:00 GMT
Robert Kanter created YARN-7162:
-----------------------------------

             Summary: Remove XML excludes file format
                 Key: YARN-7162
                 URL: https://issues.apache.org/jira/browse/YARN-7162
             Project: Hadoop YARN
          Issue Type: Bug
          Components: graceful
    Affects Versions: 2.9.0, 3.0.0-beta1
            Reporter: Robert Kanter
            Assignee: Robert Kanter
            Priority: Blocker


YARN-5536 aims to replace the XML format for the excludes file with a JSON format.  However,
it looks like we won't have time for that for Hadoop 3 Beta 1.  The concern is that if we
release it as-is, we'll now have to support the XML format as-is for all of Hadoop 3.x, which
we're either planning on removing, or rewriting using a pluggable framework.  

[This comment in YARN-5536|https://issues.apache.org/jira/browse/YARN-5536?focusedCommentId=16126194&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16126194]
proposed two quick solutions to prevent this compat issue.  In this JIRA, we're going to remove
the XML format.  If we later want to add it back in, YARN-5536 can add it back, rewriting
it to be in the pluggable framework.
