java - Pysrk 3.1.1 Py4JavaError
问题描述
我在我的 Ubuntu 机器上运行带有 java openjdk 11.0.11 的 pyspark 3.1.1。我在数据框中创建了一些随机数据
import numpy as np
n, p = (10, 4)
data = np.random.rand(n, p)
# create the dataframe
schem = StructType([StructField('col_%d'%i, FloatType(), False) for i in range(p)])
randData = spark.createDataFrame(data.tolist(), schema=schem)
randData.show()
这在我的带有 pyspark 3.0.1 的 Windows 10 机器上运行良好，但在上述系统上，我得到了这个堆栈跟踪：

我用这个简单的命令得到了同样的堆栈跟踪：
spark.CreateDataFrame([[1, 2, 3], [4, 5, 6]], ['a', 'b', 'c']).show().
知道这是怎么回事吗？
我使用从 spark.apache.org 下载的内容安装了 pyspark。JAVA_HOME设置为/usr/lib/jvm/java-11-openjdk-amd64。我的 bashrc 中有以下设置：
export PYTHONPATH=/home/ahowe42/anaconda3/bin
export SPARK_HOME=/home/ahowe42/spark-3.1.1-bin-hadoop2.7
export PYSPARK_PYTHON=ipython3
export PYTHONPATH=$PYTHONPATH:$SPARK_HOME/python
export PATH=$PATH:$SPARK_HOME/bin:$PYTHONPATH:$JAVA_HOME/jre/bin
我使用加载和初始化 pyspark
import findspark
findspark.init()
import pyspark
from pyspark.sql import SparkSession
from pyspark.sql.functions import *#avg, count, expr
from pyspark.sql.types import *
sc = pyspark.SparkContext()
spark = SparkSession(sc)
spark.sparkContext.appName = 'exploreReadWrite'
spark
解决方案
这确实是一条评论，但我还没有代表发表评论。你试过which python吗？spark 端口号的类似错误是指库之间的 python 版本不匹配。关于你的$PYTHONPATH，这将在多个地方设置，它可以被你的 shell 调用的任何进程更新——所以你知道它已经.bashrc被你的服务器从你的字符串中改变了。但是，$PYTHONPATH我认为会从左到右搜索，所以如果你的 anaconda 目录中有一个 python 运行时，我认为它会在 spark 版本之前被调用，如果你只是说py. 会不会是你的anaconda版本和spark版本使用了不同版本的python？
