Description
I'm trying to read from Parquet using Spark runner. Initial attempt failed because of version mismatch (Spark 2.3.2 use older Parquet). I tried shading parquet and avro, and it successfully read the Parquet record. However when I tried to access the record field using lambda function:
p.apply(FileIO.match().filepattern(options.getInputFile()))
.apply(FileIO.readMatches())
.apply(ParquetIO.readFiles(schema))
.apply(MapElements.into(TypeDescriptors.strings()).via(it -> it.get("name").toString()))
.apply(TextIO.write().to(options.getOutput()));
Exception in thread "main" java.lang.IllegalArgumentException: unable to deserialize org.apache.beam.sdk.transforms.MapElements$1@1292071f at org.apache.beam.sdk.util.SerializableUtils.deserializeFromByteArray(SerializableUtils.java:74) at org.apache.beam.sdk.util.SerializableUtils.clone(SerializableUtils.java:100) at org.apache.beam.runners.spark.translation.MultiDoFnFunction.<init>(MultiDoFnFunction.java:103) at org.apache.beam.runners.spark.translation.TransformTranslator$6.evaluate(TransformTranslator.java:374) at org.apache.beam.runners.spark.translation.TransformTranslator$6.evaluate(TransformTranslator.java:340) at org.apache.beam.runners.spark.SparkRunner$Evaluator.doVisitTransform(SparkRunner.java:438) at org.apache.beam.runners.spark.SparkRunner$Evaluator.visitPrimitiveTransform(SparkRunner.java:426) at org.apache.beam.sdk.runners.TransformHierarchy$Node.visit(TransformHierarchy.java:657) at org.apache.beam.sdk.runners.TransformHierarchy$Node.visit(TransformHierarchy.java:649) at org.apache.beam.sdk.runners.TransformHierarchy$Node.visit(TransformHierarchy.java:649) at org.apache.beam.sdk.runners.TransformHierarchy$Node.visit(TransformHierarchy.java:649) at org.apache.beam.sdk.runners.TransformHierarchy$Node.access$600(TransformHierarchy.java:311) at org.apache.beam.sdk.runners.TransformHierarchy.visit(TransformHierarchy.java:245) at org.apache.beam.sdk.Pipeline.traverseTopologically(Pipeline.java:458) at org.apache.beam.runners.spark.SparkRunner.lambda$run$1(SparkRunner.java:223) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.io.IOException: unexpected exception type at java.io.ObjectStreamClass.throwMiscException(ObjectStreamClass.java:1736) at java.io.ObjectStreamClass.invokeReadResolve(ObjectStreamClass.java:1266) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2078) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1573) at java.io.ObjectInputStream.readArray(ObjectInputStream.java:1975) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1567) at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:2287) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:2211) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2069) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1573) at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:2287) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:2211) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2069) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1573) at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:2287) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:2211) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2069) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1573) at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:2287) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:2211) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2069) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1573) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:431) at org.apache.beam.sdk.util.SerializableUtils.deserializeFromByteArray(SerializableUtils.java:71) ... 19 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at java.lang.invoke.SerializedLambda.readResolve(SerializedLambda.java:230) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at java.io.ObjectStreamClass.invokeReadResolve(ObjectStreamClass.java:1260) ... 41 more Caused by: java.lang.IllegalArgumentException: Invalid lambda deserialization at beamtest.examples.ParquetWordCount.$deserializeLambda$(ParquetWordCount.java:23) ... 51 more
This doesn't happen if I use SimpleFunction, but many times lambda functions are more convenient and readable
