Description
As part of Flink-Hive integration effort, it's important for Flink to access (read/write) Hive data, which is the responsibility of Hive connector. While there is a HCatalog data connector in the code base, it's not complete (i.e. missing all connector related classes such as validators, etc.). Further, HCatalog interface has many limitations such as accessing a subset of Hive data, supporting a subset of Hive data types, etc. In addition, it's not actively maintained. In fact, it's now only a sub-project in Hive.
Therefore, here we propose a complete connector set for Hive tables, not via HCatalog, but via direct Hive interface. HCatalog connector will be deprecated.
Please note that connector on Hive metadata is already covered in other JIRAs, as HiveExternalCatalog.
