> * The log statement in DataXceiver "BlockSender.ClientTraceLog.info("REQUEST_SHORT_CIRCUIT_FDS"...)"
could be cleaned up somewhat.
> * use {{FsDatasetSpi#getBlockInputStream}} and {{FsDatasetSpi#getMetaDataInputStream}}
rather than adding {{FsDatasetSpi#getShortCircuitFdsForRead}}
> * {{FileInputStreamCache.Key.equals}}: use short-circuit boolean AND
> * In FileInputStreamCache.CacheCleaner, the code "iter = map.entries().iterator()" can
be removed with the same result since the (previous) first element must be removed.
