Omkar Vinit Joshi created YARN-1363:
---------------------------------------
Summary: Get / Cancel / Renew delegation token api should be non
blocking
Key: YARN-1363
URL: https://issues.apache.org/jira/browse/YARN-1363
Project: Hadoop YARN
Issue Type: Bug
Reporter: Omkar Vinit Joshi
Assignee: Omkar Vinit Joshi
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.
