spark3 因 py4j.protocol.Py4JJavaError 而崩潰

Question

我正在嘗試從 emr-5.28.0(spark 2.4.4) 遷移到 emr-6.2.0(spark 3.0.1)，無論我做什么，spark 的最基本用法都會崩潰。

這是我的 test_pyspark.py 文件：

from pyspark.sql import SparkSession

spark = SparkSession.builder.getOrCreate()

df = spark.createDataFrame(
    [
        (1, "foo"),  # create your data here, be consistent in the types.
        (2, "bar"),
    ],
    ["id", "label"]  # add your column names here
)

df.printSchema()

我將它上傳到 S3 並使用

spark-submit --deploy-mode cluster s3://<my-s3-bucket>/test_pyspark.py

它崩潰了。

這是容器日志：

找不到任何關於

class org.apache.spark.sql.catalyst.plans.logical.UpdateAction overrides final method children

因此，任何幫助將不勝感激。

原來我們有一個導致問題的舊版本的 DeltaLake-core jar。

謝謝@stevel，您的評論確實為我指明了正確的方向
