This would be the last bit to support running multiple > _standby_ NameNodes; one of the standbys should be available for fail-over. > Mostly, this is a matter of updating how we parse configurations, some > complexity around managing the checkpointing, and updating a whole lot of > tests. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
