The error indicates that /usr/share/javadoes not have permissions that will allow you to execute it, probably because it is a directory, not an executable.
该错误表明/usr/share/java没有允许您执行它的权限，可能是因为它是一个目录，而不是一个可执行文件。
Find the location of the javaexecutable on your Ubuntu machine (probably /usr/bin/java) and change /usr/share/to point to the right place.
java在您的 Ubuntu 机器上找到可执行文件的位置（可能/usr/bin/java）并更改/usr/share/为指向正确的位置。

That's an OS permissions error. It means your user doesn't have permission to write to that directory/file. It's nothing to do with Python.
这是操作系统权限错误。这意味着您的用户无权写入该目录/文件。这与 Python 无关。

you could also try setting shell=True as the second argument in you subprocess.call(), that may work.
您也可以尝试将 shell=True 设置为 subprocess.call() 中的第二个参数，这可能会起作用。
ret = subprocess.call(shlex.split(cmd), shell=True)
cmd = /usr/share/java -cp pig-hadoop-conf-Simpsons:lib/pig-0.8.1-cdh3u1-core.jar:lib/hadoop-core-0.20.2-cdh3u1.jar org.apache.pig.Main -param func=cat -param from =foo.txt -x mapreduce fsFunc.pig
