---------------------------------
[~Apache9], Thanks for reminding . Upload patch for branch-1, the previous
one is for branch-1.3 and it may apply failed.
> And huzheng, you need to take care of the shell command. If we also want to
> introduce a flag for the grant command in shell, you need to find a proper to
> do it as the default behavior on master and branch-1 are different.
OK
> Correct the semantic of permission grant

> 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]
>
>
> 1 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, which confused
> most of HBase administrator.
> It's seems more reasonable that HBase merge multiple granted permission.
