Andrew Purtell updated HBASE-13312:
-----------------------------------
    Attachment: HBASE-13312-0.98.patch

Thanks for the review Ted.

While backporting I found changes in 0.98 needed to be more extensive, patch attached. Running
the full test suite before commit.

> The subclass of {{ScannerCallable}}, called {{SmallScannerCallable}} seems to miss calling
any of the increment methods of the {{ScanMetrics}}. The superclass does so, but the super
methods are not invoked. It emits the metrics dutifully at the end of {{next()}}, but there
are no useful numbers in it.
