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*
http://sna-projects.com/kafka/ *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.
