[HIVE-7349] Consuming published Hive HCatalog artificats in a Hadoop 2 build environment fails

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved

Description

The published Hive artifacts are built with Hadoop 1 profile. Even though Hive has Hadoop 1 and Hadoop 2 shims, some of the HCatalog Mapreduce classes are still dependent on the compiled environment.

For example, using Hive artifacts published in a Sqoop Hcatalog Hadoop 2 build environment results in the following failure

Found interface org.apache.hadoop.mapreduce.JobContext, but class was expected
java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.JobContext, but class was expected
