--------------------------------------------------------
Key: PIG-1194
URL: https://issues.apache.org/jira/browse/PIG-1194
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.5.0, 0.6.0
Reporter: Viraj Bhat
Assignee: Richard Ding
Fix For: 0.6.0
Attachments: inputdata.txt
I have a simple Pig script which takes 3 columns out of which one is null.
{code}
input = load 'inputdata.txt' using PigStorage() as (col1, col2, col3);
a = GROUP input BY (((double) col3)/((double) col2) > .001 OR col1 < 11 ? col1
: -1);
b = FOREACH a GENERATE group as col1, SUM(input.col2) as col2, SUM(input.col3)
as col3;
store b into 'finalresult';
{code}
When I run this script I get the following error:
ERROR 2055: Received Error while processing the map plan.
org.apache.pig.backend.executionengine.ExecException: ERROR 2055: Received

================================================================================
A more useful error message for the purpose of debugging would be helpful.
