Subject [jira] [Created] (MESOS-183) Included MPI Framework Fails to Start
Date Thu, 12 Apr 2012 16:11:20 GMT
Included MPI Framework Fails to Start

                 Key: MESOS-183
             Project: Mesos
          Issue Type: Bug
          Components: documentation, framework
         Environment: Scientific Linux Cluster
            Reporter: Jessica J

There are really two facets to this issue. The first is that no good documentation exists
for setting up and using the included MPI framework. The second, and more important issue,
is that the framework will not run. The second issue is possibly related to the first in that
I may not be setting it up properly. 

To test the MPI framework, by trial and error I determined I needed to run python
build and python install in the MESOS-HOME/src/python directory. Now when I try to
run nmpiexec -h, I get an AttributeError, below: 

Traceback (most recent call last):
  File "./", line 2, in <module>
    import mesos
  File "/usr/lib64/python2.6/site-packages/mesos-0.9.0-py2.6-linux-x86_64.egg/", line
22, in <module>
    import _mesos
  File "/usr/lib64/python2.6/site-packages/mesos-0.9.0-py2.6-linux-x86_64.egg/",
line 1286, in <module>
    DESCRIPTOR.message_types_by_name['FrameworkID'] = _FRAMEWORKID
AttributeError: 'FileDescriptor' object has no attribute 'message_types_by_name'

I've examined and determined that the version of protobuf it includes (2.4.1) does,
indeed, contain a FileDescriptor class in that sets self.message_types_by_name,
so I'm not sure what the issue is. Is this a bug? Or is there a step I'm missing? Do I need
to also build/install protobuf?
