Xuefu Zhang commented on FLINK-10729:
-------------------------------------
Hi [~ZhenqiuHuang], I did some initial research and found this is much involved
than on the surface. It seems that the complexity comes mostly from Hive side,
and there will probably need a prototype and design. I will spend more time on
this. Thus, if you don't mind I'm going to assign this back to myself.
Once the design is completed, I'm sure there will be many subtasks to be
created. I'd appreciate if you could help at that time.
Thanks.
> Create a Hive connector for Hive data access in Flink
> -----------------------------------------------------
>
> Key: FLINK-10729
> URL: https://issues.apache.org/jira/browse/FLINK-10729
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Affects Versions: 1.6.2
> Reporter: Xuefu Zhang
> Assignee: Zhenqiu Huang
> Priority: Major
>
> 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}}.
