Date Fri, 30 May 2014 13:06:02 GMT

     [ https://issues.apache.org/jira/browse/YARN-1366?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rohith updated YARN-1366:
-------------------------

    Attachment: YARN-1366.4.patch

Attached updated patch that address Anubhav's all comments. This patch contains only YarnClient
changes. 
The changes are
1. Added a test that covers the scenario for functionalities.
2. Added core-site.xml for test with disabling ip based check.
3. modified yarn-client pom.xml for getting yarn-common-test in test classpath.

I am not changing status for "Patch Available" since test require patch of Yarn-1365.

> The ApplicationMasterService currently sends a resync response to which the AM responds
by shutting down. The AM behavior is expected to change to calling resyncing with the RM.
Resync means resetting the allocate RPC sequence number to 0 and the AM should send its entire
outstanding request to the RM. Note that if the AM is making its first allocate call to the
RM then things should proceed like normal without needing a resync. The RM will return all
containers that have completed since the RM last synced with the AM. Some container completions
may be reported more than once.
