Description

 

hiveCatalog.createFunction(
      new ObjectPath(HiveCatalog.DEFAULT_DB, "myUdf"),
      new CatalogFunctionImpl(TestSimpleUDF.class.getCanonicalName(), new HashMap<>()),
      false);

hiveCatalog.getFunction(new ObjectPath(HiveCatalog.DEFAULT_DB, "myUdf"));

There is an exception now:

org.apache.flink.table.catalog.exceptions.FunctionNotExistException: Function default.myUdf does not exist in Catalog test-catalog.

Seems there are some bugs in HiveCatalog when use upper.

Maybe we should normalizeName in createFunction...
