> Saw StreamingIO_1 on particular perl version due to a warning in
> PigStreaming.pl. You can see the warning in any version of perl using "perl
> -w":
> {code}
> defined(%hash) is deprecated at streaming/PigStreaming.pl line 76.
> (Maybe you should just omit the defined()?)
> {code}
> In some particular version of perl, warning check is mandatory and the perl
> script just fail.
