Flink Hudi HMS Catalog problem

[melin li]

Flink SQL reads and writes Hudi and synchronizes Hive tables via the Hudi
HMS Catalog，If the hive database has both the parquet table and the hudi
table, two different flink catalogs need to be registered, causing problems.
Not very friendly for data analysts to use. Yes spark does not have this
problem, you can use spark_catalog catalog to access hudi and parquet
tables, not sure if this problem is solved in hudi or flink?

How to add permission validation? flink reads and writes hive table。

[melin li]

flink supports both sql and jar types.How can we implement a unified access
check in flink? spark supports extensions; flink lacks extensions.

Support Stored procedures

[melin li]

Supports operations like hudi/iceberg calls, such as savepoint/ checkpoint，
https://hudi.apache.org/docs/procedures/

CALL system.procedure_name(arg_1, arg_2, ... arg_n)

Based on the flink development platform, direct use of call sql to complete
some management operations, will be very convenient. hudi/iceberg can
easily customize various table actions
