Hey, I get a weird error when I try to execute my job on the cluster. Locally this works fine but running it from the command line fails during typeextraction:
input1.union(input2, input3).map(Either::<UserEvent, Long> Left).returns(eventOrLongType); This fails when trying to extract the output type from the mapper, but I wouldnt actually care about that because I am providing my custom type implementation for this Either type. The error: org.apache.flink.client.program.ProgramInvocationException: The main method caused an error. at org.apache.flink.client.program.PackagedProgram.callMainMethod(PackagedProgram.java:512) at org.apache.flink.client.program.PackagedProgram.invokeInteractiveModeForExecution(PackagedProgram.java:395) at org.apache.flink.client.program.Client.runBlocking(Client.java:250) at org.apache.flink.client.CliFrontend.executeProgramBlocking(CliFrontend.java:669) at org.apache.flink.client.CliFrontend.run(CliFrontend.java:320) at org.apache.flink.client.CliFrontend.parseParameters(CliFrontend.java:971) at org.apache.flink.client.CliFrontend.main(CliFrontend.java:1021) Caused by: java.lang.ArrayIndexOutOfBoundsException: -1 at java.util.ArrayList.elementData(ArrayList.java:418) at java.util.ArrayList.get(ArrayList.java:431) at org.apache.flink.api.java.typeutils.TypeExtractor.createTypeInfoFromInputs(TypeExtractor.java:599) at org.apache.flink.api.java.typeutils.TypeExtractor.createTypeInfoWithTypeHierarchy(TypeExtractor.java:493) at org.apache.flink.api.java.typeutils.TypeExtractor.analyzePojo(TypeExtractor.java:1392) at org.apache.flink.api.java.typeutils.TypeExtractor.privateGetForClass(TypeExtractor.java:1273) at org.apache.flink.api.java.typeutils.TypeExtractor.createTypeInfoWithTypeHierarchy(TypeExtractor.java:560) at org.apache.flink.api.java.typeutils.TypeExtractor.privateCreateTypeInfo(TypeExtractor.java:389) at org.apache.flink.api.java.typeutils.TypeExtractor.getUnaryOperatorReturnType(TypeExtractor.java:273) at org.apache.flink.api.java.typeutils.TypeExtractor.getMapReturnTypes(TypeExtractor.java:110) at org.apache.flink.streaming.api.datastream.DataStream.map(DataStream.java:550) Any ideas?
