Raghu Angadi commented on HADOOP-2528:
--------------------------------------
These extra checks are fine as long as users are ok with false negatives (when
enforcing is disabled on Namenode) or false postives (safemode). I mainly did
not want extra features (HADOOP-2531) to make these checks "as right as
possible".
