When --parallelize-phases is active, workload_setup downloads mongorestore-viewless-timeseries-compatible into mongodb/bin/. In parallel, mongodb_setup runs rm -rf ./mongodb before extracting the MongoDB tarball (download_mongodb.py#L772). Depending on timing, the rm -rf may delete the already-downloaded binary, causing pre_task to fail with:

bash: mongodb/bin/mongorestore-viewless-timeseries-compatible: No such file or directory

Affected tasks: tsbs_steady_state_low, tsbs_query_finance, tsbs_query_finance_locust, tsbs_query_genny.

Fix: Change the download path from mongodb/bin/ to custom_binaries/ so it is not wiped by mongodb_setup. One-line change to mongorestore_viewless_timeseries_binary in workload_setup.2024-05.yml.
