It appears the new "l" node role is throwing off the assertion:

127.0.0.1 29 97 44 5.37 3.48 2.53 dilm * node-0
127.0.0.1 37 97 69 5.37 3.48 2.53 dim  - node-2
127.0.0.1 27 97 42 5.37 3.48 2.53 dilm - node-1
127.0.0.1 35 97 73 5.37 3.48 2.53 dim  - node-3

Whereas the matching is looking for: (-|[dmi]{1,3}) (no l)

This reproduces for me with:

./gradlew :qa:mixed-cluster:v7.4.0#mixedClusterTestRunner --tests "org.elasticsearch.backwards.MixedClusterClientYamlTestSuiteIT" -Dtests.method="test {p0=cat.nodes/10_basic/Test cat nodes output}" -Dtests.seed=8C5A220601946023 -Dtests.security.manager=true -Dtests.locale=fr-RW -Dtests.timezone=America/Fort_Wayne -Dtests.distribution=default -Dcompiler.java=12 -Druntime.java=11

I think that your branch is not up to date with the latest master. If it were you would see 5fee557 pushed earlier today where the assertion has been changed as a reflection of functionality pushed in that test. This failure does not reproduce for me on the latest master. Maybe tell @elasticmachine to update branch?

@jasontedor that's it, I'll update the feature branch and then merge it, thanks.
