 Description   

After discussion, it was decided to simply remove the 3-node replset variant, as it is redundant. The other changes are too complicated to be worth it.


Old description

We've recently discovered that the Evergreen Distributed Correctness tests don't actually use a lot of the DSI facitilities, even though it does check out DSI repo and the Evergreen yaml file is based on the system_perf.yml file. In particular, the tests are running their own replica set on localhost, so none of the EC2 resources that DSI deploys are used for anything.

As we refactor a lot of DSI code currently, it would make it much easier if we remove the things not actually used by anyone from distributed_correctness.yml. Otherwise we spend days maintaining and trouble shooting what is actually dead code.

  • linux-3-node-replSet variant
  • "prepare environment", "bring up cluster", "restore cluster" , "destroy cluster" and "configure mongodb cluster" can be completely removed
  • Items in "run test", e.g. the ips.sh / update_run_config.sh parts of run-distributed_correctness_suite_1.sh will not work after above removals, so will need to be slightly edited.

Current assumption is that the "analyze", "upload log file" and "make test log artefact" parts are needed or might be needed in the future. They might need small edits around missing ips.sh as well.
