[CONTROLLER-1739] Dsbenchmark: Conflicting modification for test-status on install

Duplicate — Tue, 25 Jul 2023 08:24:45 +0000

This is very similar to ~~CONTROLLER-1552~~ but the transaction failure cause is different, so opening a new bug.

Benchmark is not a Bugzilla component for Controller project, so opening under Clustering component.

Upon installation of odl-mdsal-benchmark, each member tries to write initial test-status transaction. In very rare cases, two members submit at the same time, leading to "ConflictingModificationAppliedException: Node was created by other transaction".

As this is happening in config-pusher, unhandled OptimisticLockFailedException prevents creation of ModuleIdentifier

{factoryName='dsbenchmark-impl', instanceName='dsbenchmark-default'}

which leads to "Configuration Transaction failed on 2PC, server is unhealthy" and a red dot in CSIT. See job console output [0].
