> force split flag is used when a user requests region split and specifies a
> split key.
> {code}
> region.forceSplit(splitPoint);
> {code}
> We need to clear force split flag at the end of SplitRequest run. If the
> region split is successful, this parent region will go away and there is no
> need to clear this flag. But we will have problem when the split is not
> successful or rejected. Here is the case:
> 1. User requested region split at rownkey-n.
> 2. We set forceSplit in the region with rownkey-n.
> 3. The split request got rejected because the region had references.
> 4. After a while, there was a system request split for the same region.
> 5. The region would use forceSplit and rownkey-n to split. What should have
> happened is that the region split is done based on system split policy.
