### Are you willing to submit PR?

- [ ] Yes I am willing to submit a PR!

Start with ServiceControlCliSuite.scala at line 75 and reproduce the two failed tests: get zk service nodes info and delete zk service nodes info. Compare their actual empty output with the expected service-node text; done means both tests pass reliably without flaking.
