[jira] [Commented] (HBASE-7896) make rename_table working in 92/94

["Matteo Bertozzi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-7896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13583540#comment-13583540 ] 

Matteo Bertozzi commented on HBASE-7896:
----------------------------------------

on trunk/96 renaming a table means breaking snapshots (data loss)
since the snapshots relies on the data being in the "table name"

but a rename can be simulated as
{code}
disable 'tableName'
snapshot 'tableName', 'tableSnapshot'
clone 'tableSnapshot', 'newTableName'
delete_snapshot 'tableSnapshot'
{code}

[~tychang] Can you explain the use case?

> The rename_table function is very useful for our customers. However, rename_table.rb does not work for 92/94. It has several bugs. It will be useful to fix them so that users can solve their problems.
