   > @bharatviswa504 thanks for the patch. On a second thought i wonder why don't we complete authorization on the OM which receives the first request from client, this will save us the trouble of propagating credentials in rest of the call and simplify HA design.
   
   We can check Acl's on the leader OM, we cannot do checkAcls on any OM(which some times might not be leader), because think of a case like setAcl's is not applied on that OM(as it is a follower) but we are performing check Acl's.
