JiangHua Zhu updated HDFS-16069:
--------------------------------
Description:
When zkfc is working, one of the NameNode (Active) will become the Standby
state. Before the state change, this NameNode has saved some files (edit log),
these files are stored in the directory
(dfs.namenode.edits.dir/dfs.namenode.name.dir) , And will not disappear in the
short term until the status of this NameNode becomes Active again.
These files (edit log) are of little significance to the cluster.
