java.lang.NoSuchMethodError 使用 PySpark 读取 avro 文件时

Question

我正在尝试在 Dataproc 作业上使用 PySpark 运行加载 avro 文件：

spark_session.read.format("avro").load("/path/to/avro")

我遇到了流动错误：

版本：

PySpark：2.3.4
火花：2.3.4
数据处理：1.3.56-debian9
Avro: org.apache.spark:spark-avro_2.11:2.4.5

Answer 1

您看到此错误是因为您在 Spark 2.4.5 和 Spark 2.3.4 中使用 spark-avro 库，您应该使用具有 Spark 2.4.5 的 Dataproc 1.4 来解决此问题。
