> 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.
