> For Namesystem lock some parameters such as 
> "dfs.namenode.lock.detailed-metrics.enabled", 
> "dfs.namenode.read-lock-reporting-threshold-ms", 
> "dfs.namenode.write-lock-reporting-threshold-ms"
> we will support reconfigurable these parameters without namenode restart is convenient for us to check the metrics operation of FSNamesystemLock.
