xuzq commented on HDFS-14812:
-----------------------------

Thanks [~ayushtkn] for the comment.

Two reasons for this patch:
 # Some wrong words and no argument in LOG.
 # RouterState may be old (updated 1min ago) when refresh.

Update mount point is low frequency, so I think we should update routerState 
cache every time when refresh.
