> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ha, namenode
> Affects Versions: 3.0.0, 2.4.0
> Reporter: Chris Nauroth

>
> With HDFS-4816, the standby uploads the new checkpoint to the active in a
> background thread. This thread may continue to execute after transitioning
> to active or shutting down. This is marginally wasteful of bandwidth if the
> image transfer is large, and it also breaks subsequent tests on Windows since
> the thread continues to hold a lock on a file descriptor in the storage
> directory.
