Installed ambari-shell according to great post here:
can I start/stop one particular service through ambari-shell?
@Marek Martofel yes you can. Here's a full list of the commands, including commands for starting and stopping individual services.
You can also use Ambari's API to accomplishe the same task:
Hello @Henry Sowell actually, I can't find good example of how to stop particular service. It's available to start and stop ALL services at once by:
ambari-shell> services stop
ambari-shell> services start
ambari-shell also 'understands' service stop and service start but does the same.
