> The FailoverController in HADOOP-7924 needs to be able to fence off the
> current active in case it fails to transition to standby (or the user
> requests it for sanity). This is needed even for manual failover (the CLI
> should use the configured fencing mechanism). The FC needs to access the
> HDFS-specific implementations HDFS-2179, could add a common fencing interface
> (or just shell out but we may not always want to do that).
