> Configured NameNode HA. Build #435, 3-node cluster
> The Percent JournalNodes Available alert has no instances. But the JournalNode process
alert has three instances as expected.
> This happens when the alert has not run yet and the component is brought online. The
first time the alert runs, it records an OK, which is technically not a state change (since
there was no prior state). Because no state change occurred, the aggregate listener did not
fire.
