> Currently when doing splits or merge we notify quota manager about the same.
> But if quota instance is null on below call
> {code:java}
> // code placeholder
> env.getMasterServices().getMasterQuotaManager() {code}
> So the below two lines will throw unexpected exception which ideally can be
> handled.
> {code:java}
> // SplitTableRegionProcedure.java
> env.getMasterServices().getMasterQuotaManager().onRegionSplit(this.getParentRegion());
> {code}
> {code:java}
> // MergeTableRegionProcedure.java
>
> env.getMasterServices().getMasterQuotaManager().onRegionMerged(this.mergedRegion);
> {code}
