> I've been working on CRUNCH-340 to finish implementing the HCatSource and
> HCatTarget. It seems to be in a better place now that crunch only supports
> hadoop 2. I was looking to target as high of a version of hive/hcat as
> possible with minimal impact on the code base and dependencies.
> Hive 2.3.1 is out now. That relies upon hadoop 2.7.2, but HBase doesn't bump
> up to that version until HBase 2.x. Trying to run with hadoop 2.7.2 causes
> test failures in crunch-hbase. I'm not sure if that is going to cause runtime
> issues as the minicluster wouldn't even start due to a package name change in
> hadoop-hdfs (for the class StorageType) that's causing a no class found
> error.
> Hive 2.1.0 relies upon Hadoop 2.6.0, and that plays nice with HBase 1.x.
> However, the class StructField (inside TupleObjectInspector for ORC files)
> has a new abstract method added to it that would need to be implemented that
> was introduced after 2.x of Hive. Other than that everything runs fine.
> Currently Crunch is on 0.13.1 of Hive, so it's pretty far behind. I'm just
> kind of looking for feedback on the version bumps that should be targeted for
> my changes in CRUNCH-340. I wanted to take care of those first in a separate
> JIRA before introducing new code against a higher Hive version.
