> Key: IMPALA-12156
> URL: https://issues.apache.org/jira/browse/IMPALA-12156
> Project: IMPALA
> Issue Type: New Feature
> Affects Versions: Impala 4.1.2
> Reporter: Zhi Tang
> Priority: Major
>
> The Impala component known as the StateStore checks on the health of all
> Impala daemons in a cluster, and continuously relays its findings to each of
> those daemons. If the StateStore is not running or becomes unreachable, the
> cluster becomes less robust and metadata becomes less consistent as it
> changes. Therefore, implementing high availability for the Statestore is
> essential for the stability of the cluster.
