Subject [jira] [Commented] (ACCUMULO-2091) Concurrent random walk fails to rename across namespaces
Date Thu, 02 Jan 2014 21:51:52 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13860820#comment-13860820
] 

Josh Elser commented on ACCUMULO-2091:
--------------------------------------

I have a quick patch sitting locally which creates an InvalidNamespaceNameException and wraps
it with an AccumuloException instead of what currently exists which is a bit cleaner to me.

This would satisfy your concerns as we have a specific exception to catch and the exception
contains the message that they tried to rename a table across namespaces. I tried to lift
up the above InvalidNamespaceNameException to the interface but got a little worried about
the impact with all the try/catch's which just eat certain Exceptions and throw an AssertionException
instead.

> Saw the following walker log.   I think we should modify the test to detect when its
attempting to rename across namespaces and make it expect an error.  Probably should not be
getting an Accumulo exception.
