Hi,
I want to execute a pig command in embedded java program. For moment, I try
Pig in local mode. My data file size is around 15MB but the execution of
this command is very long so I think my script need optimizations...
My script :
A = LOAD 'data' USING MyUDFLoader('data.xml');
> filter_response_time_less_than_1_s = FILTER A BY (response_time < 1000.0);
> filter_response_time_between_1_s_and_2_s = FILTER A BY (response_time >=
> 1000.0 AND response_time < 1999.0);
> filter_response_time_between_greater_than_2_s = FILTER A BY (response_time >=
> 2000.0);
> star__zne_asfo_access_log = FOREACH ( COGROUP A BY
> (date_day,url,date_minute,ret_code,serveur),
