James Taylor commented on PHOENIX-1402:
---------------------------------------
Log lines to look for wrt to stats collection during splits include:
{code}
logger.debug("Collecting stats for the daughter region " +
l.getRegionInfo());
logger.debug("Collecting stats for the daughter region " +
r.getRegionInfo());
logger.debug("Committing stats for the daughter regions as part
of split " + r.getRegionInfo());
{code}
> Don't recalculate stats on split

> Rather than scan the new regions on a split (which is potentially expensive,
> and might be causing the timeouts you're seeing [~jfernando_sfdc]), we should
> instead just split up the existing guideposts between new two new regions
> based on the split point.
