Pradeep Kamath updated PIG-740:
-------------------------------
Attachment: PIG-740.patch
GruntParser was not handling double quotes within foreach blocks correctly by
incorrectly treating them the same way as single quote for the starting double
quote and not handling the end double quote - the patch addresses the bug by
treating double quotes correctly.
> Incorrect line number is generated when a string with double quotes is used
> instead of single quotes and is passed to UDF

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