Question

我正在尝试使用以下简单代码读取实木复合地板文件：

  ParquetReader<GenericRecord> reader = AvroParquetReader.<GenericRecord>builder(path).build());
  GenericRecord record = reader.read();

但是对于org.apache.avro.LogicalType却收到NoClassDefFoundError。有什么想法我做错了吗？

我在pom.xml中的版本：

    <dependency>
      <groupId>org.apache.parquet</groupId>
      <artifactId>parquet-avro</artifactId>
      <version>1.10.1</version>
    </dependency>

哦...我的avro版本错误，此组合有效

<dependency>
   <groupId>org.apache.parquet</groupId>
   <artifactId>parquet-avro</artifactId>
   <version>1.10.1</version>
</dependency>
<dependency>
    <groupId>org.apache.avro</groupId>
    <artifactId>avro</artifactId>
    <version>1.9.0</version>
</dependency>

java.lang.NoClassDefFoundError：读取Parquet时出现org / apache / avro / LogicalType
