Istvan Toth commented on HBASE-29117:
-------------------------------------
I'm going to test if removing the explicit dependency works.
I would consider that only as a last resort, as these are real direct
dependencies.
As for the anti-pattern: This is a straight regression that is not hard to fix.
(see the PRs)
I don't think we should burden downstream projects with having to fix this if
we can fix it in HBase easily.
If want HBase to be used extensively, we should make at as easy to integrate
with as possible.
