> With KNOX-2680, the Knox team introduced two major changes in Cloudera
> Manager service discovery:
> * the first is that Knox only discovers services that are actually listed in
> the given descriptor (instead of discovering the entire cluster)
> * from now on, Knox maintains an in-memory repository of discovered data
> (cluster, service, and role configs). Caffeine is used as the cache
> implementation with the default of 10 mins of cache entry TTL.
> It turns out the first improvement may cause redundant topology redeployments
> due to "missing" service discovery details while the {{Polling Configuration
> Analyzer}} finds a relevant event that belongs to a service that was not
> included in the latest discovery round.
> For now, we should disable that feature temporarily until it's clear how to
> enable and address the redundant redeployment issue.
