ramkrishna.s.vasudevan commented on PHOENIX-1584:
-------------------------------------------------
When the stats is calculated during compaction it is an absolute measure. But
during splits we have an approximation while calculating the percentage. That
leads to this variation.
> Ensure stats are correct if simultaneous split and merge

> During splits, we update the rowCount and byteCount via
> StatisticsWriter.splitStats() and at the same time compaction also updates
> the stats. So we are not able to get a consistent result for the rowCount and
> byteCount under these conditions. So for now these are not asserted when
> doing a select from the STATS table in the statistics unit tests. However on
> the client side it is asserted. All tests passes with this.
