> Key: HAMA-992
> URL: https://issues.apache.org/jira/browse/HAMA-992
> Project: Hama
> Issue Type: Question
> Components: bsp core, pipes
> Affects Versions: 0.7.1
> Environment: RASPBIAN JESSIE
> Full desktop image based on Debian Jessie
> Reporter: Chaitanya
> Labels: features, github-import, newbie

> Hello all,
> I am trying to implement apache hama on Raspberry pi model 3 to establish a
> distributed computing platform for scientific computation. I am trying to run
> hama streaming over hadoop on a single namenode but I am facing a bit of a
> difficulty in streaming my python code. I have downloaded the hama streaming
> repository from :-
> https://github.com/thomasjungblut/HamaStreaming
> I ran the examples and also HelloWorldBSP.py on Hama and they work well. But
> as soon as I switch to running my python code, the job fails.
> I am trying to run the code with the following command:-
> hama pipes -streaming true -bspTasks 1 -interpreter python -output
> /tmp/pystream-out_2/ -program /tmp/PyStreaming/BSPRunner.py -programArgs
> python.py
> Below is the log file for your reference. I hope you can find time to help me
> in this minor project:-
