> MetricsConnection has metrics for meta cache clears by server and region, and also metrics by exception type which triggered the clear. The metric by exception type is currently missing at least one instance (in AsyncRequestFutureImpl) where the cache is cleared due to an exception.
> We should do an audit of cache clear calls and ensure all the appropriate ones are tracked by exception too.
