解决jupyter连接spark，Nosuchfileordirectory:‘/opt/spark/python/pyspark/./bin/spark-submit‘

在jupyther里面执行sc = SparkContext(conf=conf)，出现：

Spark submit fails: No such file or directory: '/opt/spark/python/pyspark/./bin/spark-submit'

解决办法：

os.environ['SPARK_HOME'] = '/export/servre/spark'

填写集群的spark安装地址
