[jira] [Created] (YARN-1624) QueuePlacementPolicy format is not easily readable via a JAXB parser

Aditya Acharya created YARN-1624:
------------------------------------

             Summary: QueuePlacementPolicy format is not easily readable via a JAXB parser
                 Key: YARN-1624
                 URL: https://issues.apache.org/jira/browse/YARN-1624
             Project: Hadoop YARN
          Issue Type: Bug
          Components: scheduler
    Affects Versions: 2.2.0
            Reporter: Aditya Acharya


The current format for specifying queue placement rules in the fair scheduler allocations file does not lend itself to easy parsing via a JAXB parser. In particular, relying on the tag name to encode information about which rule to use makes it very difficult for an xsd-based JAXB parser to preserve the order of the rules, which is essential.
