liaowenrui commented on HDFS-3175:
----------------------------------
Thank you very much for your comments.
why do it was a deliberate choice not to automatically exit SM if disk space
late became available?
The NameNodeResourceChecker only check whether the disk is available or not,
whether the system is automatically exit safemode or not is determined by
NameNodeResourceMonitor.
> When the disk space is available back,Namenode resource monitor can
> automatically take off safemode.
