> For security mode, HDFS now supports that Datanodes don't require root or
> jsvc if {{dfs.data.transfer.protection}} is configured.
> Log message for {{InvalidMagicNumberException}}, we miss one case:
> when the datanodes run on unprivileged port and
> {{dfs.data.transfer.protection}} is configured to {{authentication}} but
> {{dfs.encrypt.data.transfer}} is not configured. SASL handshake is required
> and a low version dfs client is used, then {{InvalidMagicNumberException}} is
> thrown and we write log:
> {quote}
> Failed to read expected encryption handshake from client at .... Perhaps the
> client is running an older version of Hadoop which does not support encryption
> {quote}
> Recently I run HDFS built on trunk and security is enabled, but the client is
> 2.5.1 version. Then I got the above log message, but actually I have not
> configured encryption.
