> 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}}.
