> During the process of improving region normalization feature, I found that if
> region split request triggered by the execution of SplitNormalizationPlan
> fails, there is no way of knowing whether the failed split originated from
> region normalization.
> The association of particular split request with outcome of split would give
> RegionNormalizer information so that it can make better normalization
> decisions in the subsequent invocations.
> One approach is to embed metadata, such as a UUID, in SplitRequest which gets
> passed through RegionStateTransitionContext when
> RegionServerServices#reportRegionStateTransition() is called.
> This way, RegionStateListener can be notified with the metadata (id of the
> requester).
