-------------------------------
Priority: Minor (was: Major)
> Consolidate the Statestore subscriber's retry logic
> ---------------------------------------------------
>
> Key: IMPALA-9006
> URL: https://issues.apache.org/jira/browse/IMPALA-9006
> Project: IMPALA
> Issue Type: Improvement
> Components: Distributed Exec
> Affects Versions: Impala 3.4.0
> Reporter: Michael Ho
> Assignee: Michael Ho
> Priority: Minor
>
> Currently, a Statestore subscriber starts a separate thread after the initial
> registration with Statestore to periodically check if the Statestore may have
> failed and re-registered with Statestore if necessary. Similarly, the
> function {{StatestoreSubscriber::Register()}} also relies on the old Thrift
> client's retry logic to retry failed RPC attempts to Statestore. This is
> needed as the initial registration relies on this retry logic to wait for
> Statestore to startup in case an Impala daemon starts before the Statestore.
> These two retry paths may be consolidated.
