Patch v4 to update documentation for SASL as following:
Tested patch in single node secure cluster for SASL. DataNode started with
non-privileged rpc port and privileged http port. hdfs operations confirms SASL
qop.
dfs.datanode.address = 0.0.0.0:10040 (non-privileged)
dfs.datanode.http.address = 0.0.0.0:1016 (privileged)

> Datanode#checkSecureConfig should check HTTPS and SASL encryption
> -----------------------------------------------------------------
>
> Key: HDFS-13081
> URL: https://issues.apache.org/jira/browse/HDFS-13081
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode, security
> Affects Versions: 3.0.0
> Reporter: Xiaoyu Yao
> Assignee: Ajay Kumar
> Priority: Major
> Attachments: HDFS-13081.000.patch, HDFS-13081.001.patch,
> HDFS-13081.002.patch, HDFS-13081.003.patch, HDFS-13081.004.patch
>
>
> Datanode#checkSecureConfig currently check the following to determine if
> secure datanode is enabled.
> # The server has bound to privileged ports for RPC and HTTP via
> SecureDataNodeStarter.
> # The configuration enables SASL on DataTransferProtocol and HTTPS (no plain
> HTTP) for the HTTP server. The SASL handshake guarantees authentication of
> the RPC server before a client transmits a secret, such as a block access
> token. Similarly, SSL guarantees authentication of the
> HTTP server before a client transmits a secret, such as a delegation token.
> For the 2nd case, HTTPS_ONLY means all the traffic between REST client/server
> will be encrypted. However, the logic to check only if SASL property resolver
> is configured does not mean server requires an encrypted RPC.
> This ticket is open to further check and ensure datanode SASL property
> resolver has a QoP that includes auth-conf(PRIVACY). Note that the SASL QoP
> (Quality of Protection) negotiation may drop RPC protection level from
> auth-conf(PRIVACY) to auth-int(integrity) or auth(authentication) only, which
> should be fine by design.
