The Ops guy would probably be fired if he doesn't make sure the container 
runtime is up 24/7.  🙂

Well that is just relying on docker daemon to start after reboot. It may not

docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the 
docker daemon running?
systemctl start docker
docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             
STATUS              PORTS               NAMES

So your mileage varies. A proper way would be to have two instances of 
start-history-server.sh running on different hosts listening to the same Spark, 
thus avoiding a single point of failure.

Just thought about another possibility which is to containerize the history 
server and run the container with proper restart policy.  This may be the 
approach we will be taking because the deployment of such HS would be more 
flexible.

Thanks!

The scripts just launch the processes. To make any process restart on system 
restart, you would need to set it up as a system service (i.e. controlled by 
'service'). That's easy enough but out of scope for Spark itself.

Hi Users,

We found that the history server launched by using the 
"start-history-server.sh" command does not survive system reboot.  Any 
recommendation of making it always up even after reboot?

Thanks,

James
