Subject [jira] [Commented] (HCATALOG-3) Send a message on a message bus when events occur in Metastore
Date Tue, 17 May 2011 22:55:47 GMT


Jakob Homan commented on HCATALOG-3:

The activemq inclusion, particularly just for testing, concerns me as well.  Eventually, it
would be great to refactor the message sending away from JMS so that those with other messaging
solutions (*cough* *cough*) could drop those in.  It appears
the current WIP patch is quite WIP - HCatListener is overriding quite a few methods that aren't
defined in the hierarchy.  I'm also concerned about the use of the finalize method, which
is generally agreed to be evil and unreliable.  Also, it would be good to think about dependencies
such that we don't need to fire up whole metastores for these tests and can instead use mocking,
to avoid long pauses and slow tests.
