Correct way to restart presto-server service on EMR
up vote

I have to restart presto-server on EMR to load my plugin. With reference to official AWS EMR docs:
On some places they say
sudo restart presto-server
On others they say,
sudo stop presto-serverfollowed bysudo start presto-server
While Restarting a service page favours the 2nd technique above,
Note: Stop/start is required; do not use the restart command.
I have found that both work without a glitch.
Questions:
- What's the difference between
sudo restart&sudo stop+sudo start? - Why the warning against
restart? - Which one to use for
presto-server?
Platform / Frameworks:
emr-5.15.0Presto 0.212

restart does not reload the service configuration file (unfortunately, i don't remember the path to the file; this is the file which tells e.g. which user Presto runs as). Depending on the changes you introduce, this may or may not be an issue. Eg. if you are changing Presto config files or plugins, this is not an issue. If, however, you're changing the Presto service definition file, restart will not pick up your changes, whereas stop + start will.
