Lars Hofhansl commented on PHOENIX-5607:
----------------------------------------
Specifically what I meant with last comment: Once we have an API in front of
any access to the metadata stored in HBase, we can unit-test the API calls
themselves, and through that route cover many backwards compatibility scenarios
without the need to actually check in an old Phoenix jar and (somehow) use that
for testing.
[~sandeep.guggilam] points out that we start by unit-test MetaEndpointImpl
itself, right now.

> URL: https://issues.apache.org/jira/browse/PHOENIX-5607
> Project: Phoenix
> Issue Type: Test
> Affects Versions: 4.15.0
> Reporter: Lars Hofhansl
> Priority: Blocker
> Fix For: 4.16.0

>
> Filing this as a blocker for 4.16.0.
> As we've seen with the various failed attempts to release 4.15.0 Phoenix'
> backwards compatibility story is weak, and lacks tests - in fact there're no
> tests.
> We should not allow to ship 4.16.0 without improving that and without tests.
> [~ckulkarni], [~gjacoby] , FYI, what we discussed.
