> When all NameNodes become standby, EditLogTailer will retry 3 times to trigger log roll, then it will be failed and throw Exception "Cannot find any valid remote NN to service request!". After one namenode become active, standby NN still can not trigger log roll again because variable "nnLoopCount" is still 3, it can not init to 0.
