             Summary: [SBN] Disable trigger edit Log Roll for Observers
                 Key: HDFS-15616
                 URL: https://issues.apache.org/jira/browse/HDFS-15616
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Janus Chow


Currently when Observer is transitioned from StandbyState, the editLogTailer will still send the request to roll editLog to ActiveNN, which should be disabled to keep the definition of "

logRollPeriodMs" clear.

One thing I'm not sure is for a cluster with multi standby Namenode, all the standby NN will trigger the roll. Should this feature be extended to all standby NNs or implementing on observers first?
