Hi,

Can write UDF with overrides LOAD SimpleTextLoader without mapreduce, I am
bit confused with the use of mapreduce, because i am not able to get the
flow of the LOAD SimpleTextLoader when the command is invoked.

command: A = LOAD 'data' using myudf.SimpleTextLoader();

i want to now the step by step call of the functions that is called
internally.

Thanks & Regards
Chethan Prakash.

If you want to run it under a debugger, you can run it in local mode.
java -cp pig.jar  org.apache.pig.Main -x local
