How To Stop Presto
If you are using the presto-admin tool this is how to stop Presto safely:
$ presto-admin server stop
In addition these commands are also useful:
presto-admin server start
presto-admin server restart
presto-admin server status
If you are using Presto on EMR, you can restart Presto with:
sudo stop presto
sudo start presto
(If you have changed any configuration params you should do this on every node where you made a change).
The above “How To Stop Presto” information is correct for PrestoDB. But other “hard forks” of Presto may use different methods to stop and start.
