如何在php中使用spark提交执行python脚本？

Question

I am working on an PHP application using MongoDB as a database platform. Collection in MongoDB has massive volume of data .Hence I have opted for Apache Spark to generate analytics.

I need to execute spark-submit command from PHP application.But its execution doesn't return any output to PHP application.

Following is code snippet

$result=shell_exec('./bin/spark-submit examples/src/main/python/pi.py'); 
print_r($result);

Please suggest me an appropriate solution

Besides ensuring the Python script is outputting data, if you bang your head against the wall for too long you could consider using the Python script to put data into a database or file to be pulled from by PHP.
