URL: https://issues.apache.org/jira/browse/PIG-2238

Issue Type: Improvement
Affects Versions: 0.9.0
Reporter: Vivek Padmanabhan
The below is my faulty script (note the usage of alias F) for which Pig 0.9
composes not so useful message as compared to 0.8;
A = load 'input' using TextLoader as (doc:chararray) ;
B = foreach A generate flatten(TOKENIZE(doc)) as myword;
C = group B by myword parallel 30;
D = foreach C generate group,COUNT(B) as count,SIZE(group) as size;
E = order D by size parallel 5;
>F = limit F 20;
dump F;
For this script , error message in 0.9
>ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2240: LogicalPlanVisitor can
>only visit logical plan
Error message in 0.8
>ERROR 1000: Error during parsing. Unrecognized alias F
