Hi,
thanks for your reply.
I know why it hangs. I have read the code of agent/PythonExecutor.py
It blocks in the line "process.communicate()".
My start command will spawn three child processes. Maybe this line is
waiting for the three to finish? I am not very familiar with how the
communicate function works. But Vertica is a long-running process, it is
not possible for Vertica to stop. So it always timeout and get killed by
the watch-dog-thread.
Is there a way to avoid the waiting?
Thanks.

My guess is that start() does not complete or fails and gets retried few
times and then eventually fails. Can you share the agent logs?
We have a new release now 0.40 - can you port your package over to 0.40? If
you can share your package I can help you do that. In any case, only
critical change is the metainfo.xml structure where its enclosed within
"<application></application>".
http://slider.incubator.apache.org/docs/slider_specs/hello_world_slider_app.html
is a work-in-progress doc for creating an application package which will
provide you the details.

Hi,
I can start my own created package now. But it always stay IN_PROGRESS
status according to the log and after a long time it shows Failed. However,
my application runs perfectly without any errors.
Why is this? How to determine the start is completed or not?
Thanks.
