> Project: Phoenix
> Issue Type: Bug
> Environment: Ubuntu server 14.04
> Hadoop 2.6.0
> HBase 1.0.0
> Phoenix 4.4.0-HBase-1.0.0

>
> When region merge occurs, SYSTEM.STATS does not update, it will leave stale
> information behind. And then if region splits on the merged region, this may
> cause
> "org.apache.phoenix.schema.StaleRegionBoundaryCacheException: ERROR 1108
> (XCL08): Cache of region boundaries are out of date"
> after creating parallel scans since the stale information in SYSTEM.STATS
> will let guide post list not sorted in ascending order and this will cause
> scans over regions.
