Till Toenshoff commented on MESOS-1257:
---------------------------------------
Three issues have been identified so far;
1. Slave timeout when awaiting executor registration (see
https://builds.apache.org/job/Mesos-Trunk-Ubuntu-Build-Out-Of-Src-Set-JAVA_HOME/2096/consoleFull)
Should be fixed by https://reviews.apache.org/r/20819/
2. Test failure on disabled python builds --disable-python (see
https://builds.apache.org/job/Mesos-Trunk-Ubuntu-Build-Out-Of-Src-Disable-Java-Disable-Python-Disable-Webui/2097/consoleFull).
Trying to come up with a fix on that in a jiffy.
3. Test failure on disfunctional python egg.
In your specific case, it turned out that the python egg was entirely
dysfunctional due to some protoc quirks which we should really look into. To
give some more context on that as you had provided me with via IRC. The
stderr-output of the test-containerizer.py script revealed the following:
{noformat}
File
"/home/jyu/workspace/mesos-dist/build/../../mesos/src/examples/python/test_containerizer.py",
line 45, in <module>
import mesos
File "build/bdist.linux-x86_64/egg/mesos.py", line 26, in <module>
File "build/bdist.linux-x86_64/egg/_mesos.py", line 7, in <module>
File "build/bdist.linux-x86_64/egg/_mesos.py", line 6, in __bootstrap__
File "build/bdist.linux-x86_64/egg/mesos_pb2.py", line 4, in <module>
ImportError: cannot import name enum_type_wrapper
{noformat}
So even though the symptoms for 2 and 3 are equal, their causes are different.
For your specific case (3), we need to find a fix which also should fix
ExamplesTest.PythonFramework as you have reported that one fails for you as
well, which makes sense when looking at the above log-output.
