Subject [jira] [Commented] (YARN-986) RM DT token service should have service addresses of both RMs
Date Tue, 04 Mar 2014 02:28:23 GMT

    [ https://issues.apache.org/jira/browse/YARN-986?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13918951#comment-13918951
] 

Karthik Kambatla commented on YARN-986:
---------------------------------------

bq. There are some related TODOs in ClientRMProxy.setupTokens() that we put before. Search
for YARN-986. We can fix them here or separately.
Created YARN-1779 to address AMRMTokens. This JIRA is only for RMDTTokens. 

bq. getRMDelegationTokenService() API: Not sure why we are doing yarnConf.set(YarnConfiguration.RM_HA_ID,
rmId);
bq. you are only building the service against one address RM_ADDRESS.
Discussed with Vinod offline. YarnConfiguration#getSocketAddr already handles the HA case.
Updated its javadoc to reflect that. 

Addressed other comments. Again, verified manually running Oozie jobs.

> Previously: YARN should use cluster-id as token service address
> This needs to be done to support non-ip based fail over of RM. Once the server sets the
token service address to be this generic ClusterId/ServiceId, clients can translate it to
appropriate final IP and then be able to select tokens via TokenSelectors.
> Some workarounds for other related issues were put in place at YARN-945.
