Subject Re: hama streaming problem with hello world example
Date Wed, 07 Oct 2015 18:52:24 GMT
Hello Vincenzo,

this issue seems to be related to the LocalBSPRunner.
I believe the Python example should work in Pseudo Distributed Mode [1].

The error message "Traceback (most recent call last):" is caused by Python
because the file BSPPeer.py cannot be found by the interpreter.

You should also have the following error message in the log file
hama/logs/tasklogs/job_localrunner_0001/attempt_localrunner_0001_000000_0.log

Traceback (most recent call last):

  File "/..../BSPRunner.py", line 8, in <module>

    from BSPPeer import BSPPeer

ImportError: No module named 'BSPPeer'

This indicates that the parameter -cachefiles /tmp/PyStreaming/*.py is not
properly working in local mode.

I hope you can run the Python example in Pseudo Distributed Mode in the
meantime.

The Hama streaming guide also suggests to run the Python example in Pseudo
Distributed Mode [2].

Best regards
Martin
