     java.net.BindException: Address already in use

On the host where you see the above error please check if there is any other process occupied that port some how?

If yet then kill that process and then try starting the HST server again.

Find Which process is using that port 9000

# netstat -tnlpa | grep 9000

The above command will show the PID which is using the port 9000 please check what that process is and then kill it if needed.

# ps -ef | grep $PID_FROM_ABOVE_COMMAND

# kill -9  $PID_FROM_ABOVE_COMMAND

.

Alternate approach: Or try changing the SmartSense port
Ambari UI --> SmartSense --> Configs --> Operations --> Web Ui Port (default is 9000)

But better to find the process which is using the port 9000 and then stop it to ensure that SmartSense can use that port.

ps -ef | grep 9000

Please check if that process "portainer" is using port 9000?

# netstat -tnlpa | grep 85623

If yes then please try to run that process on a different port to avoid port conflict.

sudo netstat -tnlpa | grep 85623

@kanna k

It indicates that your custom application "./portainer" is already consuming the Port 9000 hence HST server can not listen to that port and that the reason HST server is not coming up.

You have two options).

1). Either make the "./portainer" application to listen to some other port ... Or to kill it (Or refer to:

http://portainer.readthedocs.io/en/stable/deployment.html )

# kill -9 85623

2). Change the HST server port to something else than 9000

Ambari UI --> SmartSense --> Configs --> Operations --> Web Ui Port (default is 9000)

You need to choose between these two options.

please tell me how to run portainer in another port....

[#9]

@kanna k

Please try this (it might or might not work as "portainer" is not a HDP product) So you will have to refer to it's documentation

# ./portainer -p :9100 --data /home/myadmin/portainer_data

.

[#10]

It might be possible that HST-Server process might be started by another user. Can you please check the content of /var/run/hst/hst-server.pid for process PID to kill that process? After killing that process, you can restart HST. We recommend starting and stopping of HST server through ambari.
