Xuan Gong commented on YARN-2211: --------------------------------- bq. setCurrnetMasterKeyData, setNextMasterKeyData methods not used Removed bq. change not needed? |----- AMRMTOKEN_SECRET_MANAGER_ROOT_ZNODE_NAME Removed bq. Fix “System.out.println(stateData.getCurrentTokenMasterKey());” in FileSystemRMStateStore Removed bq. Test: add test in restart scenario that AM issued with rolled-over AMRMToken is still able to communicate with restarted RM. testAppAttemptTokensRestoredOnRMRestart may help writing the test. Yes, will add this Testcase in next ticket YARN-2212 > RMStateStore needs to save AMRMToken master key for recovery when RM > restart/failover happens > ---------------------------------------------------------------------------------------------- > > Key: YARN-2211 > URL: https://issues.apache.org/jira/browse/YARN-2211 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Xuan Gong > Assignee: Xuan Gong > Attachments: YARN-2211.1.patch, YARN-2211.2.patch, YARN-2211.3.patch, > YARN-2211.4.patch > > > After YARN-2208, AMRMToken can be rolled over periodically.
