---------------------------------

             Summary: Parameter substitution skipped with glob on register
                 Key: PIG-4887
                 URL: https://issues.apache.org/jira/browse/PIG-4887
             Project: Pig
          Issue Type: Bug
            Reporter: Koji Noguchi


For a script with globbing on register followed by multi-line comments, parameter substitution doesn't work.
{code:title=test.pig}
register /Users/knoguchi/mydir/*.jar; 

A = load '$input' as (a1:int);
/* comment here */
store A into '$output';

{code}

Trying to run this would result in 
{panel}
org.apache.pig.backend.executionengine.ExecException: ERROR 2118: Input path does not exist: file:/Users/knoguchi/git/pig/$input
{panel}

Running with {{-dryrun}}, we can see that parameter between the globbing and the multi-line style comment is ignored.

% pig -dryrun  -param input=input.txt -param output=output.txt  test.pig

2016-05-05 14:04:34,613 [main] INFO  org.apache.pig.Main - Dry run completed. Substituted pig script is at test.pig.substituted

% cat test.pig.substituted
register /Users/knoguchi/mydir/*.jar;

A = load '$input' as (a1:int);
/* comment here */
store A into 'output.txt';
