Guanghao Zhang commented on HBASE-16990:
----------------------------------------
bq. Recently, we are trying to migrate tables from Cluster-A to Cluster-B
The normal steps of migrating tables from Cluster-A to Cluster-B are:
1. take a snapshot in Cluster-A
2. ExportSnapshot to Cluster-B
3. restore snapshot in Cluster-B
Maybe we can write the user permissions into the snapshot info. Then restore it
on Cluster-B. Any ideas? [~mbertozzi]

> 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 ?
