> Attempting to enable NameNode HA, and the wizard is stuck at initializing
> shared edits when the JournalNodes are not running. The HA wizard does start
> the JNs, but if they stop for some reason, the wizard is stuck without any
> message. The reason the wizard is stuck is that it relies on JN's JMX
> response which is not available
> {code}
> "metrics" : {
> "dfs" : {
> "journalnode" : {
> "journalsStatus" : "{\"myha\":{\"Formatted\":\"true\"}}",
> {code}
> When this is not available we should tell user why wizard has a disabled Next
> button.
