------------------------------------
Summary: Standby NN can not trigger log roll after EditLogTailer
thread failed 3 times in EditLogTailer.triggerActiveLogRoll method.
Key: HDFS-10536
URL: https://issues.apache.org/jira/browse/HDFS-10536
Project: Hadoop HDFS
Issue Type: Bug
Components: auto-failover
Reporter: XingFeng Shen
Priority: Critical
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.
