Py4JJavaError:在Jupyter笔记本中使用Pyspark试图运行使用“spark”的示例

Question

我尝试运行这些示例（例如spark/examples/src/main/python/ml/fpgrowth）_示例.py)在Jupyter笔记本里的Pypark。但是，每当我尝试执行“spark.（some function）”时，都会遇到异常。在这个例子中，确实是这样spark.createDataFrame，但我也试过了火花。阅读结果也是一样。我还尝试创建了我自己的sparkSession，并使用了已在Jupyter笔记本中启动的sparkSession，但都没有正确运行。我能找到的主要例外是AnalysisException:'java.lang.RuntimeException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient;'

代码：

# $example on$
from pyspark.ml.fpm import FPGrowth 
# $example off$
from pyspark.sql import SparkSession

if __name__ == "__main__":
    spark = SparkSession\
    .builder\
    .appName("FPGrowthExample")\
    .getOrCreate()

# $example on$
df = spark.createDataFrame([
    (0, [1, 2, 5]),
    (1, [1, 2, 3, 5]),
    (2, [1, 2])
], ["id", "items"])

例外情况：

按照以下步骤为我工作

JAVA8:https://www.guru99.com/install-java.html

阿纳康达：https://www.anaconda.com/distribution/

jupyter中的Pyspark:https://changhsinlee.com/install-pyspark-windows-jupyter/

from pyspark.sql import SparkSession

spark = SparkSession\

    .builder\

    .appName("FPGrowthExample")\

    .getOrCreate()

# $example on$
df = spark.createDataFrame([
    (0, [1, 2, 5]),
    (1, [1, 2, 3, 5]),
    (2, [1, 2])
], ["id", "items"])

df.show()
