> The reason is that HDFS throws an exception when calling
> {{ensureAppendEditlogFile}} because of some reason which causes the edit log
> output stream isn't closed. This caused that the next time we call
> {{ensureAppendEditlogFile}}, lease recovery will failed because we are just
> the lease holder.
