Thanks, your explanation is already helpful. If you say "the new HA
architecture", does this mean that the (older) ideas to extend the
backupnode functionality to provide (warm) standby as explained here
https://issues.apache.org/jira/browse/HADOOP-4539?focusedCommentId=12674954&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12674954

Or to come back to one of my previous questions: is replacing (now
deprecated) secondary namenodes with backup namenodes a future proof
idea, or should I maybe go for the new HA architecture right away?
