-------------------------------

             Summary: Correct the semantic of  permission grant
                 Key: HBASE-17472
                 URL: https://issues.apache.org/jira/browse/HBASE-17472
             Project: HBase
          Issue Type: Improvement
          Components: Admin
            Reporter: huzheng

Currently, HBase grant operation has following semantic:

{code}
hbase(main):019:0> grant 'hbase_tst', 'RW', 'ycsb'
0 row(s) in 0.0960 seconds

hbase(main):020:0> user_permission 'ycsb'
User                                                         Namespace,Table,Family,Qualifier:Permission
                                                                                         
                                                                                         
                                                          
 hbase_tst                                                   default,ycsb,,: [Permission:actions=READ,WRITE]
                                                                                         
                                                                                         
                      
4 row(s) in 0.0550 seconds

hbase(main):021:0> grant 'hbase_tst', 'CA', 'ycsb'
0 row(s) in 0.0820 seconds

hbase(main):022:0> user_permission 'ycsb'
User                                                         Namespace,Table,Family,Qualifier:Permission
                                                                                         
                                            
 hbase_tst                                                   default,ycsb,,: [Permission:
actions=CREATE,ADMIN]                                                                    
                                                           
1 row(s) in 0.0490 seconds

{code}  

Later permission will replace previous granted permissions seems confuse most of HBase administrator.

It's seems more reasonable that HBase merge multiple granted permission.
