Subject [jira] [Commented] (HBASE-6769) HRS.multi eats NoSuchColumnFamilyException since HBASE-5021
Date Thu, 13 Sep 2012 05:37:08 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13454656#comment-13454656
] 

Elliott Clark commented on HBASE-6769:
--------------------------------------

Keeping the exception and using it in hregion but not using it when sending data to the client
makes the try/catch logic a little cleaner to read. But does add a class that's no used for
much.  I'm up for whichever you think would be best.

> I think this is a pretty major usability regression, since HBASE-5021 this is what you
get in the client when using a wrong family:

> Then you have to log on the server to understand what failed.

> Assigning to Elliott because he asked.
