Review Comment:
   IMO, this does not changes the prior log except additional false log when 
setReplication failed.
   a. if status == FSDirAttrOp.SetRepStatus.SUCCESS, it logs a true since 
`status != FSDirAttrOp.SetRepStatus.INVALID`;
   b. if status == FSDirAttrOp.SetRepStatus.UNCHANGED, it also logs a true 
which is same as before.
   c. if status == FSDirAttrOp.SetRepStatus.INVALID, it logs a false which is 
additional compare to before logic.
