> HDFS-12543 introduced the notion of "open key" where when a key is opened, an
> open key entry gets persisted, only after client calls a close will this
> entry be made visible. One issue is that if the client does not call close
> (e.g. failed), then that open key entry will never be deleted from meta data.
> This JIRA tracks this issue.
