luoyuxia updated FLINK-26603:
-----------------------------
Description:
To support Hive dialect with Flink, we have implemented FLIP-123, FLIP-152.
But it also brings much maintenance burden and complexity for it mixes some
logic specific to Hive with Flink planner. We should remove such logic from
Flink planner and make it totally decouple with Flink planner.
With this ticket, we expect:
1: there won't be any specific logic to Hive in planner module
2: remove flink-sql-parser-hive from flink-table module
3: remove the planner dependency in flink-connector-hive
I'll update more details after investigation.
