------------------------------
Summary: HCatInputFormat in hive-hcatalog-core 0.13 does not
compatible with hadoop2
Key: HIVE-6970
URL: https://issues.apache.org/jira/browse/HIVE-6970
Project: Hive
Issue Type: Bug
Components: HCatalog
Affects Versions: 0.13.0
Reporter: Chao Shi
I'm developing HCatalog support for Crunch (CRUNCH-340). Crunch support both
hadoop 1 and 2, by specify profile -Phadoop-1 or -Phadoop-2. When I run my
program with hadoop2, I got the following error. I think this was intended to
be fixed by HIVE-4460.
