> 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?
