> h2. Problem
> {{TestLeaderElectorService.setUp()}} starts a three-server {{TestingCluster}} for each test, but {{tearDown()}} stops only the ResourceManagers. The test-owned ZooKeeper cluster is left open.
> h2. Solution
> * Close the cluster in a {{finally}} block after stopping the ResourceManagers, including when ResourceManager shutdown fails.
> * Test-only change; production code, HA assertions, and timeouts are unchanged.
> h2. Validation
> * Local reactor compilation passed with JDK 17 and Maven Wrapper.
> * {{TestLeaderElectorService}}: 6 tests, 0 failures, 0 errors, 0 skipped.
> * Fresh Surefire XML and {{git diff --check}} verified.
> h2. Related PR
> [PR #8874|https://github.com/apache/hadoop/pull/8874]
