> - In 2.1.3 we have the watch dog script that will shutdown the API if HBase is unresponsive
for sometime.
> - We also have the ability to auto-start per service / component
> - The two should work in conjunction for AMS
> - User needs to be alerted if Restarts are too frequent
> Alternative approach is for watch to act as a monitor and be responsible for restarting
HBase.
> This should still be a alert hook but in that case the alert can be customized for AMS
only.
> To turn on AMS auto-start append ambari.properties with
> {code}
> recovery.type=AUTO_START
> recovery.enabled_components=METRICS_COLLECTOR
> {code}
