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.
