[jira] [Resolved] (HDFS-17669) Do not reqest SASL QOP when using CryptoInput/OutputStream

     [ https://issues.apache.org/jira/browse/HDFS-17669?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Istvan Toth resolved HDFS-17669.
--------------------------------
      Assignee: Istvan Toth
    Resolution: Not A Bug

On closer inspection, Hadoop Encryption DOES use auth-conf for the key exchange.

> CryptoInputStream/CryptioOutputStream does not depend on SASL functionality, yet HDFS requests "auth-conf" QOP when negotatiating it.
> This artifically limits it to be usable only with SASL mechanisms that natively support encryption.
> Hadoop should only set the QOP if it is configured to use native SASL encryption. (i.e. if  dfs.encrypt.data.transfer is false)
