luoyuxia commented on FLINK-26360:
----------------------------------
[~MartijnVisser]Thanks for your attention. Actually, we expect it can support
hive syntax 100% support, so that hive job can migrate to flink smoothly. But
there will be some fetaures that can be supported for the limitation about
Flink, for example there's no union datatype in Flink, but hive syntax support
it.
I agree with you that it's good to open a discussion when meet ambiguity cases.
> [Umbrella] Improvement for Hive Query Syntax Compatibility
> ----------------------------------------------------------
>
> Key: FLINK-26360
> URL: https://issues.apache.org/jira/browse/FLINK-26360
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Hive
> Reporter: luoyuxia
> Assignee: luoyuxia
> Priority: Major
> Fix For: 1.16.0
>
>
> Currently, we have a support for hive synatax compatibility in flink as
> described in [FLINK-21529|https://issues.apache.org/jira/browse/FLINK-21529].
> But there're still some features we don't support or some other issues when
> using hive synatax.
> In here, we want to make a improvement to solve the issues encountered when
> using Hive dialect to make it be more smoothly when you mrigate your hive job
> to flink or enable you write flink job using hive synatax with less knowledge
> about flink sql.
> Feel free to leave your comment.
