Pig script not running?

[BlancKami]

Hello,

I followed the direction for the pig script and try to run it in ipython but it didn't output anything?

When I used

%%bash --err pig_out --bg pig -f preprocess1.pig

It did say that a job was starting in a separate thread but when I used

while True: ....: line = pig_out.readline() ....: if not line: ....: break ....: sys.stdout.write("%s" % line) ....: sys.stdout.flush()

I did not output anything and just get to a new In [] line? Is my script running at all?

Thanks for your help! I really need the feature matrices for my model.

Note I skipped the plotting because there was a errno 2 file not found with my hdfs.ls() . Not sure if that matters.
