["Zheng Hu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-16990?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15889424#comment-15889424 ] 

Zheng Hu commented on HBASE-16990:
----------------------------------

[~jerryhe], [~esteban], Thanks for your relpy.  To sum up, the following can be improved: 
1.    Dump  table schema with ACLs , other than just ACLs .  
2.    Maybe we can integrate the dumper to the hbase shell, and reuse hbase-shell framework .
3.    Better to provide ut .

En .. I'll try to provide another patch.

> 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 ?
