Hi Noelia, Why don’t you try to identify the process by “ps -ef |grep 8000” then simply kill it?
Phong De : Noelia Osés Fernández [mailto:no...@vicomtech.org] Envoyé : jeudi 14 décembre 2017 15:56 À : u...@predictionio.incubator.apache.org Objet : Error: "unable to undeploy" Hi, The first time after reboot that I train and deploy my PIO app everything works well. However, if I then retrain and deploy again, I get the following error: [INFO] [MasterActor] Undeploying any existing engine instance at http://0.0.0.0:8000 [ERROR] [MasterActor] Another process might be occupying 0.0.0.0:8000<http://0.0.0.0:8000>. Unable to undeploy. [ERROR] [TcpListener] Bind failed for TCP channel on endpoint [/0.0.0.0:8000<http://0.0.0.0:8000>] [WARN] [HttpListener] Bind to /0.0.0.0:8000<http://0.0.0.0:8000> failed [ERROR] [MasterActor] Bind failed.

Shutting down. I thought it was possible to retrain an app that was running and then deploy again. Is this not possible? How can I kill the running instance? I've tried the trick in handmade's integration test but it doesn't work: deploy_pid=`jps -lm | grep "onsole deploy" | cut -f 1 -d ' '` echo "Killing the deployed test PredictionServer" kill "$deploy_pid" I still get the same error after doing this.
