ivankelly opened a new pull request #1230: ProxyForwardAuthDataTest shouldn't reuse pulsar client URL: https://github.com/apache/incubator-pulsar/pull/1230 This test was flaking due to the pulsar client being reused. The test starts a proxy service, subscribes to a topic, stops the proxy, starts a new proxy and tries to subscribe again. If using the same client for both connections, the client will have an open connection to the first proxy, which, when the proxy is stopped, will be closed by netty asynchronously. This can race with the second subscription attempt, and cause it to fail with ConnectionClosedException. Specifically, if the subscription attempt runs before the netty callback runs, the subscription attempt will try to subscribe on a dead connection. The immediate fix for this test, to stop the flaking, is just to use a different client for each attempt.
