Thejas M Nair commented on PIG-2487:
------------------------------------
It does throw an error if you forget to specify params, for example -
{code}
$ cat t.pig
l = load $INP using PigStorage(':');
dump l;
$ bin/pig -x local t.pig

Unexpected internal error. Undefined parameter : INP
{code}
Can you show an example where it does not throw this error ?
