Description

The parquet-hadoop-bundle is not a real dependency but a mere packaging
of three parquet modules to create an uber jar. The Parquet community
created this artificial module on demand by HIVE-5783 but the
benefits if any are unclear.

On the contrary using the uber dependency has some drawbacks:

• Parquet souce code cannot be attached easily in IDEs which makes debugging sessions cumbersome.
• Finding concrete dependencies with Parquet is not possible just by inspecting the pom files.
• Extra maintenance cost for the Parquet community adding additional verification steps during a release.

The goal of this JIRA is to replace the uber dependency with concrete dependencies to the respective modules:

• parquet-common
• parquet-column
• parquet-hadoop
