Subject [jira] [Commented] (HBASE-5415) FSTableDescriptors should handle random folders in hbase.root.dir better
Date Thu, 23 Feb 2012 23:01:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5415?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13215164#comment-13215164
] 

stack commented on HBASE-5415:
------------------------------

Whats difference between miscellaneous dirs under hbase.rootdir and an actual table directory
that is missing its .tableinfo file?

We're changing our API when we remove TEE from public methods?

> I faked an upgrade on a test cluster using our dev data so I had to distcp the data between
the two clusters, but after starting up and doing the migration and whatnot the web UI didn't
show any table. The reason was in the master's log:

> I don't think we need to show a full stack (just a WARN maybe), this shouldn't kill the
request (still see tables in the web UI), and why is that a TableExistsException?
