Lars George commented on HBASE-13312:
-------------------------------------
[~apurtell] When running my book example (see
https://github.com/larsgeorge/hbase-book/blob/master/ch03/src/main/java/client/ScanCacheBatchExample.java,
just run it against a locally started HBase instance) against a 1.3.1 today, I
noticed the small scanner still reports zero RPC, but should say one, no? Am I
missing something? Do we need to revisit?
> SmallScannerCallable does not increment scan metrics

> 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.
