> Key: IMPALA-6644
> URL: https://issues.apache.org/jira/browse/IMPALA-6644
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 2.11.0
> Reporter: Mala Chikka Kempanna
> Assignee: Pooja Nilangekar
> Priority: Minor
> Labels: ramp-up, supportability
> Fix For: Impala 3.1.0
>
>
> In the latest and previous versions, statestore in it's default logging
> reports only when it fails to send heartbeat to any host.
> There is no way to confirm if Statestore is indeed continuing to heartbeat in
> all passing conditions, except for turning on debug logs, which becomes too
> noisy. But at the same time its important to know statestore is indeed
> heartbeating.
> The suggestion here is to add a metric in statestore metric page and also
> print the same in log every once in a minute(or any configurable
> time-frequency), reporting the last heartbeat timestamp and last heartbeat
> host(optional).
