pyspark用pipe管道调用bash脚本时，遇到Permission Denied问题

当用pyspark在CDH的yarn集群上运行时，用pipe管道调用bash脚本若遇到如下问题

"/usr/lib64/python2.7/subprocess.py", line 1234, in _execute_child raise child_exception OSError:
[Errno 13] Permission denied

解决：

遇到该问题首先想到应该是没有执行权限。

给bash脚本添加执行权限，

chmod +x xx.sh命令

重新提交spark任务，如若还有该问题，则可能该脚本还需要可读或者可写 则设置该脚本所在的目录src权限，

chmod 777 -R src
