[jira] [Commented] (YARN-2383) Add ability to renew ClientToAMToken

    [ https://issues.apache.org/jira/browse/YARN-2383?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14096060#comment-14096060 ] 

Xuan Gong commented on YARN-2383:
---------------------------------

Make the ClientToAMToken renewable after a configurable period of time. AM will send the renewDate in allocate call. RM can send back the new renewDate if needed thru the allocate.
At AM side, create a ClientToAMTokenCache ,which is singleton. The  ClientToAMTokenCache is used to save the master-key and renewDate of the ClientToAMToken, and the ClientToAMTokenCache will be used in ClientToAMTokenSecretManager in AM side to help save and retrieve the master-key. With using ClientToAMTokenCache, we do not need to change any public API and codes in both AM and client.
