> Stack-provided upgrade checks need to be loaded from a provided JAR when
> Ambari Server starts up. Currently, upgrade checks are loaded synchronously,
> scanning the entire classpath for classes matching {{UpgradeCheck}} in the
> package {{org.apache.ambari.server.checks}}. This can be extremely slow and
> cause Ambari Server to fail to start within a reasonable amount of time. The
> proposed changes for this issue are as follows:
> - Move to an asynchronous model for scanning the classpath for instances of
> {{UpgradeCheck}}
> - Allow stacks to provide their own plugin directory & JAR for loading SPI
> implementations of {{UpgradeCheck}}
