[~ajayydv]
I log very generic message when DataInputStream is empty. Would you like to
change or handle any?
{code}
LOG.debug("Failed to read SASL message from client at " +
peer.getRemoteAddressString() + ". Likely client has closed the socket", e);
{code}
Currently, SaslExceptions are throwable in DataXceiver and these are logged as
error in the log.
My only concern is log spam.

[~kpalanisamy] thanks for the patch, stack-trace in description seems to be
from handshake failure. I think its ok to log handshake failure but may be we
can improve the message if handshake fails.

> Ambari checks datanode liveness by simply connecting to data transfer port.
> But this connection will be closed after a successful TCP handshake without
> any data transfer. Due to which datanode encountered EOFExcetion when reading
> an encrypted message from the closed socket.
> This issue addressed in HDFS-9572. But not handled for encrypted data
> transfer(SASL message).
