-Re: 0.95 and 0.96 remaining issues
Nick Dimiduk 2013-06-24, 23:04
I want to see initial data type APIs ship out with 0.95.2. A patch for
ordered byte serialization is up (HBASE-8201) and is nearing steady-state.
However, sershe is the only person who's left feedback. I just posted an
early patch for the data type API itself (HBASE-8693). It should get some
eyes from all manor of interested parties, but I'll settle for folk from
Phoenix for now.
Should these tasks be escalated to criticals in order to grab attention?
Additional comments inline.

It would be a shame to not get a decision on this in for 0.96.

With the creation of the new list, noticing these issues is going to push
further back-burner. Nannying this stuff should retain focus. I'll
volunteer to track on these issues as I see them.
Notice though that some of the more recent failures are caused by lack of
disk space on the Jenkins build host.
