Flink Jira Bot updated FLINK-11970:
-----------------------------------
Labels: auto-deprioritized-major auto-unassigned stale-minor (was:
auto-deprioritized-major auto-unassigned)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> TableEnvironment#registerFunction should overwrite if the same name function
> existed.

> Currently, it would throw exception if I try to register user function
> multiple times. Registering udf multiple times is very common usage in
> notebook scenario. And I don't think it would cause issues for users.
> e.g. If user happened to register the same udf multiple times (he intend to
> register 2 different udf actually), then he would get exception at runtime
> where he use the udf that is missing registration.
