----------------------------------
Hi Daryn, if my understanding of this jira is correct, HDFS-4258 is to address
this kinds of path-change related issues.
> Clients should not retain leases on moved files
> -----------------------------------------------
>
> Key: HDFS-4437
> URL: https://issues.apache.org/jira/browse/HDFS-4437
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 0.23.0, 2.0.0-alpha, 3.0.0
> Reporter: Daryn Sharp
> Assignee: Daryn Sharp
> Priority: Critical
>
> Moving open files and/or parent directories of open files will rewrite the
> leases to the new path. The client is not notified so future stream
> operations will fail. However, as long as the client keeps its lease active
> it will have a "lock" on the file in its new location. This is not good for
> a daemon.
> Leases should be released after the file is moved.
