---------------------------------------------
Summary: RBF: Support port based selective encryption from routers.
Key: HDFS-17025
URL: https://issues.apache.org/jira/browse/HDFS-17025
Project: Hadoop HDFS
Issue Type: New Feature
Components: hdfs, rbf
Reporter: Simbarashe Dzinamarira
HDFS-13541 implemented based selective encryption in the Namenode.
{noformat}
This feature allows HDFS to selectively enforce encryption for both RPC
(NameNode) and data transfer (DataNode). With this feature enabled, NameNode
can listen on multiple ports, and different ports can have different security
configurations. Depending on which NameNode port clients connect to, the RPC
calls and the following data transfer will enforce security configuration
corresponding to this NameNode port. This can help when there is requirement to
enforce different security policies depending on the location where the clients
are connecting from.{noformat}
This ability for selective encryption should still be available to clients when
they connect to routers instead of directly to the namenode.
This implemented can leverage a lot of the code written for the Namenode
selective port based encryption. A lot of the changes are in hadoop-common, eg.
HDFS-13566.
