> Hbase Streaming Scan is a feature recently added to trunk.
> In this feature, an asynchronous scanner pre-loads data to the cache based on
> its size (both row count and size in bytes). In one of the locations where
> the scanner polls an item from the cache, the variable holding the estimated
> byte size of the cache is not updated. This affects the decision of when to
> load the next batch of data.
> A bug fix patch is attached - it comprises only local changes to the
> ClientAsyncPrefetchScanner.java file.
