Key: PIG-2156
URL: https://issues.apache.org/jira/browse/PIG-2156
Project: Pig
Issue Type: Bug
Reporter: Gianmarco De Francisci Morales
Assignee: Gianmarco De Francisci Morales
Pig generates an error with this script:
{code}
grunt> a = load 'a.txt';
grunt> b = group a all;
grunt> c = foreach b generate COUNT(a) as sum;
grunt> d = limit a 1 * c.sum;
[main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1200: <line 4, column 14>
mismatched input '*' expecting SEMI_COLON
{code}
The reason is the parser chooses the wrong alternative.
