[jira] Created: (PIG-1462) No informative error message on parse
problem
No informative error message on parse problem
---------------------------------------------
Key: PIG-1462
URL: https://issues.apache.org/jira/browse/PIG-1462
Project: Pig
Issue Type: Bug
Affects Versions: 0.7.0
Reporter: Ankur
Consider the following script
in = load 'data' using PigStorage() as (m:map[]);
tags = foreach in generate m#'k1' as (tagtuple: tuple(chararray));
dump tags;
This throws the following error message that does not really say that this is a bad declaration
org.apache.pig.impl.logicalLayer.FrontendException: ERROR 1000: Error during parsing. Encountered "" at line 2, column 38.
Was expecting one of:

[jira] Commented: (PIG-1462) No informative error message on parse
problem
Posted by "Ashutosh Chauhan (JIRA)" <ji...@apache.org>.

Ashutosh Chauhan commented on PIG-1462:
---------------------------------------
This has come up before. As noted on PIG-798 correct way to achieve this is
{code}
grunt> in = load 'data' using PigStorage() as (m:map[]);
grunt> tags = foreach in generate (tuple(chararray)) m#'k1' as tagtuple;
grunt> dump tags;
{code}
We probably need to add a note about casting in cookbook. Also, need to generate better error message.

Right, the JIRA is for adding a better error message that doesn't leave a user guessing
