[HDFS-16755] TestQJMWithFaults.testUnresolvableHostName() can fail due to unexpected host resolution

• Type: Bug
• Status: Resolved
• Priority: Minor
• Resolution: Fixed
• Affects Version/s: 3.4.0, 3.3.5
• Fix Version/s: 3.4.0, 3.3.5
• Component/s: test
• Labels: pull-request-available

Environment

Running using both Maven Surefire and an IDE results in a test failure.  Switching the name to "bogus.invalid" results in the expected behavior, which depends on an UnknownHostException.

• Target Version/s: 3.4.0, 3.3.5

Description

Tests that want to use an unresolvable address may actually resolve in some environments.  Replacing host names like "bogus" with a IETF RFC 2606 domain name avoids the issue.
