> When I ran the following Pig script on the command line (pig -c cluster -latest p_11),
Pig returns immediately without doing any processing.  When I entered the script line by line
into GRUNT, after I entered the second line, I had to type one extra ";" in addition to the
original one in order for Pig to accept the line.  In the end, Pig gave me the correct results.
> Here is the script, p_11:
> {code}
> A = load '/user/pig/tests/data/singlefile/studenttab10k';
> B = stream A through `python ./python/MySimpleStreamApp.py --upper` as (name, age, gpa);
> store B into 'results_11';
> {code}
> Here is the python streaming script, MySimpleStreamApp.py:
> {code}
> #!/usr/bin/python
> import sys
> import optparse
> def main():
>     p = optparse.OptionParser()
>     p.add_option('--upper', '-u', action="store_true")
>     options, arguments = p.parse_args()
>     line = sys.stdin.readline()
>     while line:
>         if options.upper == True:
>             line = line.upper()
>         sys.stdout.write(line)
>         line = sys.stdin.readline()
> if __name__ == '__main__':
>     main()
> {code}
