@yaooqinn, the module label should be flink, not hive.

oops..

@yaooqinn shall we make this a KPIP and let the corresponding issues follow the naming pattern like [SUBTASK][KPIP-X]?

[yaooqinn]

I am not sure that we can propose a KPIP on the status of this ticket, which seems not to meet the requirement of a KPIP.

In fact, we shall not create subtasks for KPIP-2 as it has been resolved. [SUBTASK][#2100] may be enough?
