      Description

      DataXceiver tries to establish secure channels via sasl when dfs.encrypt.data.transfer is turned on. However, domain socket traffic seems to be unencrypted therefore the client cannot communicate with the data node via domain sockets, which makes short circuit reads unfunctional.
