[jira] [Created] (HDFS-5353) Short circuit reads fail when dfs.encrypt.data.transfer is enabled

Haohui Mai created HDFS-5353:
--------------------------------

             Summary: Short circuit reads fail when dfs.encrypt.data.transfer is enabled
                 Key: HDFS-5353
                 URL: https://issues.apache.org/jira/browse/HDFS-5353
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Haohui Mai


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.
