There is no "native" HA solution for HDFS at the moment.
"External" HA solutions, like Coudera's may exist.
Cannot speak for everybody, but I know at least one different approach.

Hi.
This is exactly the goal (long term). To evolve BN into StandbyNode,
which will be able to take over when main NN dies without restarting
anything else.
And the only remaining step is to implement fail-over mechanism.
Just to clarify, for the near future, the only HA option is Cloudera DRDB
approach.
Correct?
