(*ASE#processResult* -> *EES#becomeStandby* -> *AS#transitionToStandby* -> *RM#transitionToStandby*) and (RM#serviceStop -> RM.super#serviceStop -> *RM.super#stop* -> AS#stop -> *AS#serviceStop* -> *EES#serviceStop* -> *ASE#quitElection*) IIUC, Karthik's patch on YARN-1929 partially solve this problem, but not completely. Please correct me if I get wrong. Thanks. > Both RM stuck in standby mode when automatic failover is enabled > ---------------------------------------------------------------- > > Key: YARN-1861 > URL: https://issues.apache.org/jira/browse/YARN-1861 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Affects Versions: 2.4.0 > Reporter: Arpit Gupta > Assignee: Vinod Kumar Vavilapalli > Priority: Critical > > In our HA tests we noticed that the tests got stuck because both RM's got into standby state and no one became active. -- This message was sent by Atlassian JIRA (v6.2#6252)
