>
> When both short-circuit read and SASL on DataTransferProtocol are enabled,
> the server side tries to negotiate SASL on the operation to allocate a new
> shared memory slot. However, the transport for this operation is the Unix
> domain socket (not TCP), and the client always assumes that Unix domain
> socket traffic is trustworthy. The end result is that the server side still
> attempts SASL negotiation, and it fails with an exception while erroneously
> trying to parse the domain socket address as if it were a network address.
> The read succeeds, but only because we fallback to a read through the
> DataNode TCP server. It's not a short-circuit read.
