Subject [jira] Created: (PIG-267) Don't substitute parameters inside comments
Date Fri, 13 Jun 2008 08:14:44 GMT
Don't substitute parameters inside comments
-------------------------------------------

                 Key: PIG-267
                 URL: https://issues.apache.org/jira/browse/PIG-267
             Project: Pig
          Issue Type: Improvement
            Reporter: Amir Youssefi


A script with $x in comments fails because Pig thinks it's an undefined parameter. One approach
to address it is to skip substitution for comments. 

java.lang.RuntimeException: Undefined parameter : x

        at org.apache.pig.tools.parameters.ParameterSubstitutionPreprocessor.parsePigFile(ParameterSubstitutionPreprocessor.java:106)
        at org.apache.pig.tools.parameters.ParameterSubstitutionPreprocessor.genSubstitutedFile(ParameterSubstitutionPreprocessor.java:86)
