      Description

      HDFS-1623 gives a high level architecture and design for hot automatic failover of the NN. Branch HDFS-1623 was merged into trunk for tactical reasons even though the work for HA was not complete, Branch HDFS-1623 contained mechanisms for keeping a standby Hot (ie read from shared journal), dual block reports, fencing of DNs, Zookeeper library for leader election etc. This Umbrella jira covers the remaining work for HA and will link all the jiras for the remaining work. Unlike HDFS-1623 no single branch will be created - work will proceed in parallel branches.
