Date Wed, 18 May 2016 23:09:13 GMT

     [ https://issues.apache.org/jira/browse/YARN-4957?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sean Po updated YARN-4957:
--------------------------
    Attachment: YARN-4957.v7.patch

YARN-4957.v7.patch addresses Carlo's comments and fixes the checkstyle and javadoc issues.
Two check-style issues with regards to method length will remain - these are pre-existing,
and a refactor will be out of the scope of this JIRA.

> Currently submitReservation returns a ReservationId if sucessful. This JIRA propose adding
a getNewReservation in ApplicationClientProtocol for the following reasons:
>   * Prevent zombie reservations in the face of client and/or network failures post submitReservation
>   * Align reservation submission with application submission
