> Remove shared instances of the shared {{ReadWriteLock}} found in {{ClusterImpl}}. For now, the lock can remain private and full encapsulated inside of {{ClusterImpl}}, but it's use and reference across the rest of Ambari should be removed.
> This is part of the effort to refactor/remove the (mostly) unnecessary locks in memory. The shared instance of this lock is the number one reason that Ambari "deadlocks" when under load.
