> *Possible reason:*
> Datanodes send reports with negative used space.
> On the datanode side {{CachingSpaceUsageSource}} has a method
> {{decrementUsedSpace}} which decrements total used size by a particular
> value. The total used size is in turn taken from a delegate
> {{SpaceUsageSource}}. If the latter fails to return a value,
> {{decrementUsedSpace}} will subtract from 0, hence a negative value.
> A failure to get used size might be caused by smth like:
