Subject AbstractGroupScan.getScanStats()
Date Mon, 13 Jul 2015 16:55:46 GMT
Method org.apache.drill.exec.physical.base.AbstractGroupScan.getScanStats()
has a body that throws a "This must be implemented" exception.

Why isn't getScanStats()simply an abstract method?

(Is there any case in which a subclass doesn't need to implement the
method (i.e., where that method won't ever be called for that subclass)?)
