I'm actually not convinced this is a problem. I don't actually think it's 
possible for RetriesExhaustedWithDetailsException to clear the meta cache

> RetriesExhaustedWithDetailsException can create a pathological feedback loop

> RetriesExhaustedWithDetailsException currently obscures that the underlying 
> exception(s) may be OperationTimeoutExceededException. Because of this, we 
> can still run into situations where slow request can trigger a flood of meta 
> cache clearing exceptions, and hotspot the meta table. 
>  
> We should update our exception handling logic to special case these 
> exceptions, and explicitly check to see if the underlying root cause for the 
> request failures was due to an operation timeout.
