python - Py4JJavaError : An error occurred while calling o389. parquet 尝试将 rdd 数据帧写入本地目录上的 parquet 文件

Question

我正在尝试使用 Jupyter notebook 中的以下代码将数据框写入本地目录中的 parquet 文件:

rdd1 = rdd.coalesce(partitions)

schema1 = StructType([StructField('date', DateType()), StructField('open', FloatType()), StructField('high', FloatType()),
           StructField('low', FloatType()),StructField('close', FloatType()),StructField('adj_close', FloatType()),
           StructField('volume', FloatType()), StructField('stock', StringType())])

rddDF = spark.createDataFrame(rdd1,schema=schema1)

spark.conf.set("spark.sql.parquet.compression.codec", "gzip")

rddDF.write.parquet("C:/Users/"User"/Documents/File/Output/rddDF")

我收到以下错误:

我检查了我所有的系统变量:Hadoop_home、Java_home、Spark_home、Scala_home、Pyspark_python、Pyspark_driver_python。

我已经安装了带有 Hadoop v2.7 和 Scala 2.12.4 的 Spark v3.2，更新到 v2.12.10。我在笔记本中使用 Python 3.8。

我已经尝试降级到 Python 3.7，但这并没有解决问题。

我不确定还可以尝试什么来修复此错误。任何帮助将不胜感激。

更新:我尝试修复数据类型，但错误仍然存​​在。

然后我对创建 Dataframe 的方式进行了以下更改:

rddDF = spark.createDataFrame([rdd1],schema=schema1)

这消除了 TypeError:

StructType can not accept object 'close' in type <class 'str'>

现在我的错误显示:

我在 Windows 机器上解决问题的方法是将 Hadoop 的“bin”目录(在 HADOOP_HOME 指定的目录中)添加到 PATH 变量。

当我的 HADOOP_HOME 不存在，或者没有指向正确的位置时，我得到一个错误(现在我忘记了)。但是在我解决这个问题之后，我遇到了你遇到的那个。在尝试使用 7 个不同版本的 Hadoop 文件(winutils.exe 和 hadoop.dll)后，我遇到了“路径”问题。当一个 OSS 项目依赖于一堆其他项目时，这就是一种困惑，它们都有自己解决依赖关系的方式。

我从提升的 Powershell 提示符下运行它，重新启动我的 VsCode 实例(这是我运行我的 Jupyter Notebooks 的地方)，然后我能够保存 parquet 文件。

[Environment]::SetEnvironmentVariable("PATH", "$env:PATH;$env:HADOOP_HOME\bin", 'Machine')
