> While verifying Spark 4.0.0 RC2, I consistently saw YARN test {{AmIpFilterSuite#testProxyUpdate}} failing in my environment. The test is written to eventually expect a {{ServletException}} from {{getProxyAddresses}} after 5 seconds of retries, but I never received this exception.
> This test and the corresponding {{AmIpFilter}} were introduced in SPARK-48238 as a fork of the Hadoop implementation to resolve a dependency conflict. However, it seems this test had a small bug in the way it was adapted into the Spark codebase. The {{AmIpFilter#getProxyAddresses()}} logic may either return an empty set or throw a {{ServletException}} if it can't find any valid configured proxies. The Hadoop test's assertion allows for either of these conditions, but the Spark implementation strictly requires an exception to be thrown.
