How Do You Rename a Table in HBase?

问题:

I'm trying to rename a table in HBase but the help in the shell doesn't have a rename command. move, mv and other common culprits don't appear to be it, either.

回答1:

To rename a table in HBase, apparently you have to use snapshots. So, you take a snapshot of the table and then clone it as a different name.

In the HBase shell:

disable 'tableName'
snapshot 'tableName', 'tableSnapshot'
clone_snapshot 'tableSnapshot', 'newTableName'
delete_snapshot 'tableSnapshot'
drop 'tableName'
