Subject [jira] [Updated] (YARN-3039) [Aggregator wireup] Implement ATS app-appgregator service discovery
Date Tue, 17 Mar 2015 19:29:39 GMT

     [ https://issues.apache.org/jira/browse/YARN-3039?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Junping Du updated YARN-3039:
-----------------------------
    Attachment: YARN-3039-v7.patch

Sync up offline with [~zjshen], with a few updates in v7 patch, comparing with v6:
1. In ApplicationMaster, replace callback handler in AMRMClientAsync with registering timelineClient
into AMRMClientAsync.
2. comment out RetryFilter for Jersey client in TimelineClientImpl for getting rid of two
layers retry, more cleanup work may do later.
3. Add TODO (in YARN-3038) for cleanup aggregator (collector) info in NM in failed over case.

Verify end to end test can pass.

> Per design in YARN-2928, implement ATS writer service discovery. This is essential for
off-node clients to send writes to the right ATS writer. This should also handle the case
of AM failures.
