Description
This is the design for automatic hot HA for HDFS NameNode. It involves use of HA software and LoadReplicator - external to Hadoop components, which substantially simplify the architecture by separating HA- from Hadoop-specific problems. Without the external components it provides warm standby with manual failover.
