Subject [jira] [Commented] (YARN-2212) ApplicationMaster needs to find a way to update the AMRMToken periodically
Date Wed, 30 Jul 2014 20:10:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-2212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14079876#comment-14079876
] 

Jian He commented on YARN-2212:
-------------------------------

- AMS#registerApplicationMaster changes not needed.
- May not say stable now.
{code}
  @Stable
  public abstract Token getAMRMToken();
{code}
-   ApplicationReport#getAMRMToken for unmanaged AM needs to be updated as well.
- we can move the AMRMToken creation from RMAppAttemptImpl to AMLauncher? 
- {code} Use newInstance instead. 
BuilderUtils.newAMRMToken(
          amrmToken.getIdentifier(), amrmToken.getKind().toString(),
          amrmToken.getPassword(), amrmToken.getService().toString())
{code}
- Test AMRMClient automatically takes care of the new AMRMToken transfer. 
- Please run on real cluster also and set roll-over interval to a small value to make sure
it actually works.
