Subject [jira] [Updated] (HBASE-16990) Shell tool to dump table schemas and table privileges
Date Wed, 02 Nov 2016 07:54:58 GMT

     [ https://issues.apache.org/jira/browse/HBASE-16990?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

huzheng updated HBASE-16990:
----------------------------
    Description: 
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 ?
