             Summary: Replace parquet-hadoop-bundle dependency with the actual parquet modules
                 Key: HIVE-25296
                 URL: https://issues.apache.org/jira/browse/HIVE-25296
             Project: Hive
          Issue Type: Improvement
            Reporter: Stamatis Zampetakis
            Assignee: Stamatis Zampetakis
             Fix For: 4.0.0


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
