Subject [jira] [Created] (HDFS-9899) The implication of auth-conf is not followed in optimized HDFS data transfer encryption
Date Fri, 04 Mar 2016 03:46:40 GMT
Jerry Chen created HDFS-9899:
--------------------------------

             Summary: The implication of auth-conf is not followed in optimized HDFS data
transfer encryption
                 Key: HDFS-9899
                 URL: https://issues.apache.org/jira/browse/HDFS-9899
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: encryption
    Affects Versions: 2.6.0
            Reporter: Jerry Chen


HDFS-6606 provided an optimized way of HDFS data transfer encryption. The optimized encryption
is build on top of SASL wrap/unwrap when auth-conf is configured.

When user specifies auth-conf, he wants both integrity and confidential. While the current
implementation of the optimization implements only confidential with AES/CTR and there is
no integrity grantees, which means the implications of auth-conf were not strictly followed.
