Richard Zowalla closed STORM-3473.
----------------------------------
Resolution: Won't Fix
Hive is gone with 2.6.0
> Hive can't read records written from HiveBolt

> Issue Type: Bug
> Components: storm-hive
> Affects Versions: 2.0.0
> Reporter: Alex Parrill
> Priority: Major

> I'm trying to stream items from storm into hive using the HiveBolt, but Hive
> does not seem to see the records at all.

> logs either.
> Anyone know what's up? I can get more info if needed.
