> I was just playing around the code, trying to capture "Top k" table metrics
> from MetaMetrics, when I bumped into this issue. Though currently we are not
> capturing "Top K" table metrics, but we can encounter this issue because of
> the "Top k Clients" that is implemented using the LossyAlgo.

> RegionServer gets aborted due to a NPE from MetaTableMetrics coprocessor. The
