[FLINK-5833] [table] Support for Hive GenericUDF
Type: New Feature
Priority: Major
Components: table, udf
Problem definition: Make Flink call Hive User-Defined Functions, support
for simple hive Generic UDFs.
Design:
1. This patch is based on FLINK-5881 and FLINK-5832, we need variable
arguments to call hive udfs. We also need a HiveFunctionWrapper in FLINK-5832
to create Hive Generic UDFs.
1. Added a ScalarFunction called HiveGenericUDF to call Hive Generic UDFs.
Use primitive java object inspectors for the generic UDFs.
1. Moved the code to flink-hcatalog
Impact Analysis:
A new feature, had few impacts on exsting features. We updated hcatalog
dependencies from 0.12.0 to 0.13.0.
Test:
`mvn clean verify` is done on local.
