title: Quartz setup failure in Azure App Service
body: <p>I have a Azure App service up and Running. Spring boot app is deployed. When I try to add Quartz scheduler setup in Spring boot app, it works fine in local. But when we move to Azure app, scheduler setup not booted with the below message.</p>
  
  <p>Basically it looks for host name, in Azure App service can we find the host name? Any configuration required to resolve hostname?  </p>
  
  <pre><code>2020-05-08 11:35:57.155 ERROR 123 --- [main] org.quartz.impl.StdSchedulerFactory      : Couldn't generate instance Id!
  org.quartz.SchedulerException: Couldn't get host name!at org.quartz.simpl.SimpleInstanceIdGenerator.generateInstanceId(SimpleInstanceIdGenerator.java:36)at org.quartz.impl.StdSchedulerFactory.instantiate(StdSchedulerFactory.java:1247)at 
  </code></pre>
  
  <p>Please Note:
  Commenting the properties in Quartz will set default value but we need to go with Auto approach
  org.quartz.scheduler.instanceId=AUTO</p>
