Benoy Antony updated HDFS-5910:
-------------------------------
Attachment: HDFS-5910.patch
An enhancement is done on dataTransferProtocol to decide this based on
pluggable Resolver. This is the same resolver introduced in HADOP-10221
The DFSClient is modified to look into its local config in addition to the
encryption requirement indicated by Namenode to decide whether to encrypt the
data transfer.
The NN is modified to return encryption key to the clients even if encryption
is not turned on.
The datanode is modified to consult with the resolver in addition to
_dfs.encrypt.data.transfer_ value
> Enhance DataTransferProtocol to support encrypted and plain-text communication
