Description

While working on YARN-11360, I noticed a few problems in TestClientRMService that made it difficult to work with. Tests do not guarantee that servers they start up get shutdown. If an individual test fails, then it can leave TCP sockets bound, causing subsequent tests in the suite to fail on their socket bind attempts for the same port. There is also a file generated by a test that is leaking outside of the build directory into the source tree.
