-----------------------------------
Summary: Remove locally stored files (edit log) when NameNode
becomes Standby
Key: HDFS-16069
URL: https://issues.apache.org/jira/browse/HDFS-16069
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: JiangHua Zhu
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.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.
