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.
> Add ability to renew ClientToAMToken
