--------------------------------

TestHCM fails in trunk currently.

I ran TestMasterObserver locally with patch and it passed.

> If user sets batching in Scan object, ClientSmallScanner may return unexpected result

different Results to correspond to different rows.
> Small scan with batching should be disallowed.
