Pig should not crash when it encounters an unknown function during interactive
use
----------------------------------------------------------------------------------
Key: PIG-3
URL: https://issues.apache.org/jira/browse/PIG-3
Project: Pig
Issue Type: Bug
Environment: hadoop 13.1, hacked pig
Reporter: Ted Dunning
I get this. The crash is unfortunate when all that happened is that I should
have capitalized count.
grunt> z = foreach y generate group, count(y);
java.lang.RuntimeException: Function count not found.
