Jerry He commented on HBASE-16990:
----------------------------------

The patch itself looks good.  The concern is that we try to consolidate into the shell because standalone rb scripts can become out-of-sync and stale quickly and no test coverage. Also there is substantial overlap in functionality with user_permission.
I am going to be neutral on this one. It's ok if people find it useful with this rb tool.

> Recently,  we are trying to migrate tables from Cluster-A to Cluster-B,  I found that HBase lack some useful tools :
> 1.  dump table schema,  like mysqldump in mysql
> 2.  dump table privileges,  like pt-show-grants in mysql provided by Percona. 
> I think we can add a dump sub-command looks like (JUST simple demo) : 
> {code}
> $ ./bin/hbase dump  -t test_table  --with-privileges  > ~/test_table.hsh
> $ cat ~/test_table.hsh
> create 'test_table', {NAME=>'f1'} 
> grant 'test_user', 'RW', 'test_table'
> {code}
> Maybe I can contribute ...  :)
> How do you think ?
