    • Release Note:
      Introduced a new command, "hdfs dfsadmin -rollEdits" which requests that the active NameNode roll its edit log. This can be useful for administrators manually backing up log segments.

      Description

      This seems like it would also be helpful outside of the context of HA, but especially so given that the standby can currently only read finalized log segments.
