Description

I have a simple Pig script which loads integer data and does a Bincond, where it compares, (col1 eq ''). There is an error message that is generated in this case, but it does not specify the line number in the script.

MYDATA = load '/user/viraj/myerrordata.txt' using PigStorage() as (col1:int, col2:int);

MYDATA_PROJECT = FOREACH MYDATA GENERATE ((col1 eq '') ? 1 : 0) as newcol1,
                                         ((col1 neq '') ? col1 - col2 : 160000)
                                                        as time_diff;

dump MYDATA_PROJECT;

==========================
It would be good if the error message has a line number and a copy of the line in the script which is causing the problem.

Attaching data, script and log file.
