Subject [jira] [Updated] (YARN-1363) Get / Cancel / Renew delegation token api should be non blocking
Date Fri, 13 Dec 2013 23:33:07 GMT

     [ https://issues.apache.org/jira/browse/YARN-1363?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhijie Shen updated YARN-1363:
------------------------------

    Attachment: YARN-1363.4.patch

Fix test failures and findbugs warnings.

TestJHSSecurity failure is however, not related. Ran it locally, and the failure happened
on trunk as well. Will file another jira to track it.

> Today GetDelgationToken, CancelDelegationToken and RenewDelegationToken are all blocking
apis.
> * As a part of these calls we try to update RMStateStore and that may slow it down.
> * Now as we have limited number of client request handlers we may fill up client handlers
quickly.
