Thanks [~huaxiang].
bq. t will be better to avoid these false alarms by keeping the lock in cleaner.
Right. One alternative way is to eat the FNFE in that partition after confirming it is expired
(But it is difficult to do this after HBASE-16981 is introduced). Now I think it is fine to
retain the lock in cleaner. Upload a new patch V3 to address this.
