Summary: Hama streaming
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
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 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:-
