--------------------------------------
Assignee: (was: Hrishikesh Gadre)
> For kudu-jepsen scenario, add parameters to induce more frequent fail-over
> events on the server side
> ----------------------------------------------------------------------------------------------------
>
> Key: KUDU-2034
> URL: https://issues.apache.org/jira/browse/KUDU-2034
> Project: Kudu
> Issue Type: Task
> Affects Versions: 1.4.0
> Reporter: Alexey Serbin
> Priority: Major
> Labels: consistency, kudu-jepsen, newbie
>
> Currently, the set of parameters for the back-end components is almost
> standard -- everything is set to defaults, but the experimental flags are
> enabled and only the following tserver flags are set to something 'special'
> to speed up the test:
> {noformat}
> --heartbeat_interval_ms
> --raft_heartbeat_interval_ms
> --heartbeat_max_failures_before_backoff
> {noformat}
> Let's set parameters to induce frequent re-election/fail-over events at the
> server side. The idea is to bring in set of parameters used by certain tests
> in {{src/kudu/integration-tests}}. E.g., {{catalog_manager_tsk-itest.cc}}
> contains an example of parameters to enable frequent re-elections among
> masters; the raft-related part can be used as a starting point to update
> tserver's parameters for kudu-jepsen.
> An additional step might be injecting latency into tservers' operations.
