将Flink DataStream写到Iceberg表:NoSuchMethodError:DataStream

Question

我试图将flink数据存储到冰山表中，如下所示：

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

然后我得到了错误：

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

   ...

我检查了jar的内容，它包括所需的类型$PrimitiveBuilder类：

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

当我检查源代码时，在idea中发现了错误：

库源与TypeToMessageType类的字节码不匹配

但其他课都没问题。

我试图删除maven存储库和重新导入项目中的iceberg-parquet.jar和parquet-column.jar，并试图禁用Idea的Lombok插件，但没有效果。

版本: CDH 6.3.2 Flink 1.11.2 Iceberg 0.11.0

Answer 1

我解决了这个问题。其原因是jar冲突，具体来说，是parquet-hadoop.jar(hive-exec 2.3.4)和iceberg-parquet.jar(0.11.0)。
