我们在单节点RHEL7机器上安装了ClouderaCDH6.2，该机器附带了默认的Python2.7。为了运行pyspark/spark submit作业，我们必须在虚拟环境（/home/user/r1\u i5/bin/python是venv path）中使用python3.7。
当我在主节点中运行pyspark shell命令时 >>> wordCounts.saveAsTextFile("/user/test/wordCount_output.txt") ，我犯了一个错误 Cannot run program "/home/user/R1_I5/bin/python": error=13, Permission denied with Blacklisting behavior can be configured via spark.blacklist.*. 详细日志如下：

错误如下所示，

Blacklisting behavior can be configured via spark.blacklist.*.
