AWS datasync: Updated Hadoop DataNode port documentation
Summary
Clarified default DataNode ports for Hadoop 3.x, 2.x, and secure Kerberos clusters.
Security assessment
Specifies secure cluster configurations (Kerberos with privileged ports), aiding proper network security setup.
Evidence
DataNode port (defaults are 9866 for Hadoop 3.x, 50010 for Hadoop 2.x, and 1004 for secure clusters using Kerberos with privileged ports)
