> MetricsTableWrapperAggregateImpl has a thread that periodically updates the
> values.
> It seems that once the region server is online and the meta is assigned if
> there are no store files the Optional values here
> {code}
> mt.maxStoreFileAge = Math.max(mt.maxStoreFileAge,
> store.getMaxStoreFileAge().getAsLong());
> mt.minStoreFileAge = Math.min(mt.minStoreFileAge,
> store.getMinStoreFileAge().getAsLong());
> {code}
> is not available and thus throwing NoSuchElementException and the thread
> dies. It never updates the values till the RS is alive.
