lei w updated HDFS-16083:
-------------------------
Description: When the Observer NameNode is turned on in the cluster, the
Active NameNode will receive rollEditLog RPC requests from the Standby NameNode
and Observer NameNode in a short time. Observer NameNode's rollEditLog request
is a repetitive operation, so should we forbid Observer NameNode trigger
active namenode log roll ? We 'dfs.ha.log-roll.period' configured is 300( 5
minutes) and active NameNode receives rollEditLog RPC as shown in
activeRollEdits.png (was: When the Observer NameNode is turned on in the
