Kevin Minder updated KNOX-88:
-----------------------------
Description:
In Hadoop 2 DFS client will retry the calls to the various nodes configured to
be part of namenode HA. Thought needs to be given to if this should be
supported in the gateway or on the client. In addition if this is supported in
the gateway there needs to be though given to a one-off HDFS mechanism vs a
generic gateway capability.
