Unknown parameter causes pig to exit without message
----------------------------------------------------
Key: PIG-680
URL: https://issues.apache.org/jira/browse/PIG-680
Project: Pig
Issue Type: Bug
Reporter: Andreas Neumann
Priority: Minor
This pig script:
-- REGISTER $unknown;
x = LOAD 'nn' AS x:chararray;
DUMP x;
I run like this:
> java -jar ../../../../Pig/pig.jar -x local -file nn.pig
and pig does nothing, just exits without doiung anything.
But if I remove the $ from the first line of the script, then:
> java -jar ../../../../Pig/pig.jar -x local -file nn.pig

(def)
Similarly if I define the unknown parameter on the command line, it works fine:
> java -jar ../../../../Pig/pig.jar -x local -file nn.pig -param unknown=1

It seems that undefined parameters cause pig to exit without doing anything...
even if they are within a comment...
