Write Flink DataStream to Iceberg Table：NoSuchMethodError: org.apache.parquet.schema.Types$PrimitiveBuilder.as

I try to write a flink datastream to a iceberg table, as below:

val kafkaStream = new KafkaDataSource(parameter, new PacketSchema).getStream(env)
val dataStream = kafkaStream.flatMap(new NullPacketFilter).map(FilteredPacket.from(_).toRow).javaStream

FlinkSink.forRow(dataStream, FilteredPacket.schema)
  .tableLoader(tableLoader)
  .build

then I get error:

2021-02-18 18:12:12,086 WARN  org.apache.hadoop.util.NativeCodeLoader [] - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

   ...

I have checked the content of jar, it includes the required Types$PrimitiveBuilder class:

2651 Fri Feb 19 08:32:10 CST 2021 org/apache/parquet/schema/Types$PrimitiveBuilder.class
3101 Fri Feb 19 08:32:12 CST 2021 org/apache/flink/hive/shaded/parquet/schema/Types$PrimitiveBuilder.clas

when I check the source code, found error in idea:

Library Source does not match the bytecode for class TypeToMessageType

but all other class is ok.

I tried to delete iceberg-parquet.jar and parquet-column.jar in my maven repository and reimport project, and tried to disable Idea's Lombok plugin - but has no effect.

version: CDH 6.3.2 Flink 1.11.2 Iceberg 0.11.0

I've resolved the problem. The reason is jar conflicts, specifically, the parquet-hadoop.jar(hive-exec 2.3.4) and iceberg-parquet.jar(0.11.0)
