------------------------------------
Failure was unrelated to the current patch:

java.lang.RuntimeException: commitTransaction was called but
openTransactionCalls = 0. This probably indicates that there are unbalanced
calls to openTransaction/commitTransaction

> Native Parquet Support in Hive

> Key: HIVE-5783
> URL: https://issues.apache.org/jira/browse/HIVE-5783
> Project: Hive
> Issue Type: New Feature
> Components: Serializers/Deserializers
> Reporter: Justin Coffey
> Assignee: Justin Coffey
> Priority: Minor
> Fix For: 0.13.0

> Problem Statement:
> Hive would be easier to use if it had native Parquet support. Our
> organization, Criteo, uses Hive extensively. Therefore we built the Parquet
> Hive integration and would like to now contribute that integration to Hive.
> About Parquet:
> Parquet is a columnar storage format for Hadoop and integrates with many
> Hadoop ecosystem tools such as Thrift, Avro, Hadoop MapReduce, Cascading,
> Pig, Drill, Crunch, and Hive. Pig, Crunch, and Drill all contain native
> Parquet integration.
> Changes Details:
> Parquet was built with dependency management in mind and therefore only a
> single Parquet jar will be added as a dependency.
