I am getting an error when using the Table API with ScalarFunction. This is previously reported here (https://issues.apache.org/jira/browse/FLINK-7490) as loading a wrong class loader and is reported as fixed. But the issue persists even after using the latest code from 1.3 branch.
>From some of my experiments, this might be a potential place where the issue is, but not sure. https://github.com/apache/flink/blob/master/flink-libraries/flink-table/src/main/scala/org/apache/flink/table/functions/utils/UserDefinedFunctionUtils.scala#L746 Our application is such that the ScalarFunction is defined and instantiated in a different package from where the topology is executed. Any direction on how to work around this or what I am doing wrong is much appreciated! Thanks, Rakesh org.apache.flink.api.common.InvalidProgramException: Table program cannot be compiled.
