> Sometimes there are discrepancies between what the stack reports as being live vs Ambari reports as live.
> This comes from the fact that liveness is tracked by the service master differently than simply process up/down, which Ambari reports.
> Strictly speaking, Ambari reports both, but how UI is presenting it now creates confusion.
