使用pycharm连接虚拟机的python环境，编写pyspark，简单的wordcount程序，报错如下：

/export/server/anaconda3/envs/pyspark/lib/python3.8/site-packages/pyspark/bin/spark-class: line 71: export/server/jdk/bin/java: No such file or directory
/export/server/anaconda3/envs/pyspark/lib/python3.8/site-packages/pyspark/bin/spark-class: line 97: CMD: bad array subscript
Traceback (most recent call last):

    sc = SparkContext(conf=conf)
  File "/export/server/anaconda3/envs/pyspark/lib/python3.8/site-packages/pyspark/context.py", line 201, in __init__
    SparkContext._ensure_initialized(self, gateway=gateway, conf=conf)
  File "/export/server/anaconda3/envs/pyspark/lib/python3.8/site-packages/pyspark/context.py", line 436, in _ensure_initialized
    SparkContext._gateway = gateway or launch_gateway(conf)
  File "/export/server/anaconda3/envs/pyspark/lib/python3.8/site-packages/pyspark/java_gateway.py", line 107, in launch_gateway
    raise PySparkRuntimeError(
pyspark.errors.exceptions.base.PySparkRuntimeError: [JAVA_GATEWAY_EXITED] Java gateway process exited before sending its port number.

解决方法如下：

window系统下和linux下的java环境冲突了，在python代码指定java的环境变量即可

import os
os.environ['JAVA_HOME'] = "/usr/local/jdk1.8"   # 改成自己的jdk路径

运行成功：
