> 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.
