> We often execute several scripts in parallel and log the messages into one log file.
> If got error , we can not identify which pig script is causing it. So add a MDC with name "pig_script_file_name" and add %X{pig_script_file_name} into log4j configurations, we will surely identify the errorous pig script.
> the patch is attached.
