Pig streaming with Bash Shell?

[Alex Wang <wa...@gmail.com>]

Hi,

Does anyone know if Bash shell works with Pig streaming the same way as
Python? I've been struggling with it without success.

Here is the bash code (filter.sh)

#!/usr/bin/env bash
command /dev/stdin -arguments > /dev/stdout
exit 0

And in the pig script, I did

DEFINE filter `filter.sh`
INPUT (stdin using PigStreaming(','))
OUTPUT (stdout using PigStreaming(','))
SHIP ('filter.sh');

outdata = STREAM indata THROUGH filter;


I can't figure out what's wrong with the code above. But outdata is simply
an empty tuple. Can anyone help? Thanks!
