Subject [jira] [Commented] (HBASE-12054) bad state after NamespaceUpgrade with reserved table names
Date Tue, 23 Sep 2014 17:53:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14145128#comment-14145128

Matteo Bertozzi commented on HBASE-12054:
-----------------------------------------

[~jmhsieh] you are looking at the trunk patch, take a look at branch-1 there is a new "data"
table added to the upgrade migration. In trunk the migration test is gone but the main code
is still there (blame on jimmy HBASE-11611). I think the migration tool is supposed to be
removed from trunk tool. In trunk the patch is just removing the list of reserved names.

> If 94 has a table called "data" NamespaceUpgrade will fail to bring that table up and
the generated layout will be dirty with stuff like "/hbase/data/.data" and so on.
> (the reserved names that we have no longer apply in 96+ since the data is separate from
the root dir)
