                 Key: PIG-740
                 URL: https://issues.apache.org/jira/browse/PIG-740
             Project: Pig
          Issue Type: Bug
          Components: grunt
    Affects Versions: 0.1.0
            Reporter: Viraj Bhat
            Priority: Minor
             Fix For: 0.1.0


Consider the Pig script with the error that a String with double quotes 
"www\\." is used instead of a single quote 'www\\.' in the UDF 
string.REPLACEALL()

{code}
register string-2.0.jar;
A = load 'inputdata' using PigStorage() as ( curr_searchQuery );

B = foreach A {
        domain = string.REPLACEALL(curr_searchQuery,"^www\\.",'');
        generate
        domain;
        };

dump B;
{code}

I get the following error message where "Line 11" points to the end of file. 
The error message should point to "Line 5".
