环境变量PYSPARK_PYTHON和PYSPARK_DRIVER_PYTHON

我最近安装了pyspark。它已正确安装。当我在python中使用以下简单程序时，出现错误。

>>from pyspark import SparkContext
>>sc = SparkContext()
>>data = range(1,1000)
>>rdd = sc.parallelize(data)
>>rdd.collect()

在运行最后一行时，出现错误，其关键行似乎是

[Stage 0:>                                                          (0 + 0) / 4]18/01/15 14:36:32 ERROR Executor: Exception in task 1.0 in stage 0.0 (TID 1)
org.apache.spark.api.python.PythonException: Traceback (most recent call last):

Exception: Python in worker has different version 2.7 than that in driver 3.5, PySpark cannot run with different minor versions.Please check environment variables PYSPARK_PYTHON and PYSPARK_DRIVER_PYTHON are correctly set.

我在.bashrc中有以下变量

export SPARK_HOME=/opt/spark
export PYTHONPATH=$SPARK_HOME/python3

我正在使用Python 3。

顺便说一句，如果您使用PyCharm，则可以添加PYSPARK_PYTHON和PYSPARK_DRIVER_PYTHON运行/调试以下每个图像的配置

您应该在中设置以下环境变量$SPARK_HOME/conf/spark-env.sh：

export PYSPARK_PYTHON=/usr/bin/python
export PYSPARK_DRIVER_PYTHON=/usr/bin/python

如果spark-env.sh不存在，可以重命名spark-env.sh.template
