    Attachment: hadoop-7938.txt

Patch attached.   Aside from the tests, manually failed over with fencing via hadadmin using

Will file a jira for passing fromSvc as an argument to the fencing script instead of relying
on it being configured, and for being able to use logical dfs.ha.namenode.id instead of rpc

> 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).
