Hi Rekhi,
Rekha, actually :-)
I did not quite get this.
I know how to pass a param name and value from command line to pig
scripts and access them. But how do we pass the param name from pig
script to UDF? What will the syntax of the STORE function look like?
something like below
pig command: ... -param CONFIG_FILE='<your_path_here>'..
STORE A in 'somefile' USING MyStorageUDF(CONFIG_FILE);
Thanks,
Satish

You can send the config files as -params or use -param_file with allconfigs and
read them as $Config_file1, pass them to the UDF from your pig script.Thanks!

I have actually written my own UDF to store data. I need to pass a
config file to this UDF. Currently I have hardcoded the config file name
inside the UDF.
Now I want to use the same UDF for various config. Therefore, I wanted
to pass a filename as an argument.

By API, PigStorage delimiter needs to be single byte character.For your
requirement you can possibly extend Utf8StorageConverter/PigStorage.
Or is it possible to parse the file by the byte representation of the your
string and using with \u? Crazy thought this.., you will have to alter
functionality.

Is there a way to pass a string as an argument to the STORE function?
For example: STORE A in 'somefile' USING PigStorage("<STRING>")
