> {code:java}
> //OzoneManagerLock
> private final Map<Class<? extends Resource>,
> Pair<Map<Resource, Striped<ReadWriteLock>>, ResourceLockTracker>>
> resourcelockMap;
> {code}
> The resourcelockMap above is
> - inefficient: use a Map (the outer map) for only two elements.
> - hard to read/understand: too many layers
> - Apache Commons Pair (see HDDS-15908).
> - Not type safe: ResourceLockTracker is generic
