Subject Re: Problem initializing pipes in HamaStreaming
Date Thu, 26 Sep 2013 20:03:10 GMT
Hi Roman,

if you are running Hama in local mode, it will not use HDFS anyway.

You can find all Hama configuration files in the *conf* folder.

$ll hama/conf/
total 56
-rwxr-xr-x groomservers*
-rwxr-xr-x hama-default.xml*
-rwxr-xr-x hama-env.sh*
-rwxr-xr-x hama-site.xml*
-rwxr-xr-x log4j.properties*

Probably you should setup the Pseudo Distributed Mode [1] in hama-site.xml.

But the task log would be very interesting.

Normally you should find it in *hama/logs/tasklogs*.
e.g., hama/logs/tasklogs/job_201309262134_0001/attempt_201309262134_0001_000000_0.log

You should also find task logs in your *temp* folder.
But this location will depend on your operation system.
e.g., in OSX
/private/tmp/hadoop-YOURUSER/bsp/local/groomServer/attempt_201309262134_0001_000000_0/work/tasklogs/

By the way do you have python3.2 installed? :-)
$ python --version
Python 3.2.5
$ python3.2 --version
Python 3.2.5

May I ask which operation system do you use?

Martin
