That is correctly, the Jenkins UI will not show any info about the
gearman queue. If job is pending in Jenkins that means it's been
added to the gearman queue and has been moved to the jenkins build

jenkins queue.
Hmm. What happens when you manually start a build by click on the
build icon in the jenkins UI?
If I click the build icon in the jenkins UI, the job can run. Wired,
isn't it ?
Thanks.
I'm wondering if maybe your labels are configured correctly for your
jobs and slaves. Are there any labels on the job or the nodes
(master or slaves)? I think the jobs would be in a pending state if
there are labels on nodes and jobs but they do not match. I would
check to see if there are any labels on the jobs and if there are
then I would remove all of the labels and try again. There are step
by step directions on how to setup the gearman-plugin in the jenkins
wiki[1] which also shows you how to debug by viewing the gearman
server queue and function registrations. Try to make sure the
functions are registered correctly and that the job is in the queue
after you run the gear-client command.
A couple of questions:
What version of Jenkins are you running? I think openstack runs on
1.565.3
Also I don't think we've ever tested Jenkins and the gearman server
running on the same machine or VM. Maybe one thing you can try is to
run them on separate VMs?
I don't have any label, and only a master, no slave.
My jenkins is 1.609.1.
The whole problem is described here:
http://paste.openstack.org/show/405051/
Please help to check and see.
BTW, I post the problem to #openstack-infra IRC channel. You can join
into that meeting if you'd like to.
Thanks.

Hello Tang, Openstack slaves only have a single executor so
what you are probably seeing is due to using build slaves that
have multiple executors. There were a few bugs[1] that was
fixed recently around these types of deadlock issues. The new
gearman-plugin release[2] contains fixes for those issues. Also
if you want to test the gearman-plugin with Jenkins
independently of zuul you can use the simple
gearman-plugin-client[3] to send jobs your gearman server to see
if the jobs get built.

Hi Zaro,
Thanks for the reply.
But I updated the gearman plugin to 0.1.2, and used the
gearman-plugin-client to submit jobs.
# python gear_client.py -s localhost
--function=build:noop-check-communication
Sat Jul 25 14:16:57 2015
Sending job: build:noop-check-communication to localhost with
params={'OFFLINE_NODE_WHEN_COMPLETE': 'false', 'uuid':
'08ad7a195237493d91eea55789e76128'}
Waiting for jobs to finish.................................
It doesn't work. The job submitted by the client is also pending.
BTW, I cannot see the job submitted by client in my Jenkins GUI.
Is that correct ?
Thanks.
