> Testing Infrastructure for network partitioning

> Key: HDDS-4237
> URL: https://issues.apache.org/jira/browse/HDDS-4237
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Reporter: Rui Wang
> Priority: Major
>
> Network partitioning can cause brian-split case where there are two leaders
> exist. We need some sort of testing Infrastructure/framework to simulate such
> case and verify whether our SCM HA implementation can achieve strong
> consistency under partitioned network.
> There might be two ways suggested by Mukul Kumar Singh:
> a) Blockade tests, blockade is a docker based framework where the
> network for one DN can be isolated from the other
> b) MiniOzoneChaosCluster - This is a unit test based test, where a
> random datanode was killed and this helped in finding out issues with
> the consistency.
> We might need similar solution for SCM: block SCM leader network and also
> increase timeout to make old leader do not turn into candidate.
