Executing the pig commands

Question

Hello Baljinder,

Thanks for your response.

I have a query for you. Everytime I need to hardcode the path (highlighted in red color) while executing manually the pig commands. Do we have any provision or mechanism where the path can be set as a environment variable and call the variable instead of hard coding the path. In case if you have solution can you please send me the step by step process .

grunt> std_dtls = LOAD 'hdfs://localhost:8020/user/edureka/SourceFiles/Pig/student_details.txt' USING PigStorage(',') as (id:int,firstname:chararray,lastname:chararray,age:int,phoneno:long,place:chararray);

grunt> emp_dtls = LOAD 'hdfs://localhost:8020/user/edureka/SourceFiles/Pig/employee_details.txt' USING PigStorage(',') as (id:int,firstname:chararray,age:int,place:chararray);

grunt> std_emp_dtls_cogroup = COGROUP std_dtls by age,emp_dtls by age;

grunt> DUMP std_emp_dtls_cogroup

Dear Narayana,

Hope you are doing great.

Yes you are correct here, you have to do this steps only to Run Pig jobs, because this is the location where we have installed PIG.

Please let us know if you have any other issue.
