Release Note:

Hide
When a split is requested on a Region, the RegionServer hosting that Region will now consult the configured SplitPolicy for that table when determining if a split of that Region is allowed. When a split is disallowed (due to the Region not being OPEN or the SplitPolicy denying the request), the operation will *not* be implicitly retried as it has previously done. Users will need to guard against and explicitly retry region split requests which are denied by the system.
