------------------------------------
hi [~elgoiri]

This is kind of a readahead buffer that reads at least this much data from the
DN, right?
{quote}
This buffer is not a readahead buffer. it is a request outputstream buffer
where request params ared placed in. Request parms include block,blockToken,
clientName, startOffset, len, verifyChecksum, cachingStrategy.
And buffer need not so big.
> Make buffer of BlockReaderRemote#newBlockReader#BufferedOutputStream
> configurable
