        The failover thread in HAStressTestHarness will invoke failover periodically with fixed sleep time. The msBetweenFailovers is set to 1000 ms for TestSeveralNameNodes.

                for (int i = 0; i < nns; i++) {
                  int next = (i + 1) % nns;
                  ...
                  cluster.transitionToStandby(i);
                  cluster.transitionToActive(next);
                  ...
                  Thread.sleep(msBetweenFailovers);
        

        Retry proxy of client have sleep time exponential to number of retries on failover. The client is possible to sleep up to around 15 seconds if it repeatedly fails on the operation. The client may not get enough effective run time due to this.

        If we set time between failover to greater value, we might not get enough failovers kicking in while test threads are doing operations. I think it would be better to set smaller maximum sleep time for clients by setting dfs.client.failover.sleep.max.millis to make test stable and shorter.

            String  SLEEPTIME_BASE_KEY = PREFIX + "sleep.base.millis";
            int     SLEEPTIME_BASE_DEFAULT = 500;
            String  SLEEPTIME_MAX_KEY = PREFIX + "sleep.max.millis";
            int     SLEEPTIME_MAX_DEFAULT = 15000;
        

        In addition, test should exit immediately after all test threads finish the work.

        I updated the patch. Though the possibility is low, clients could exhaust retries in test run time. The max retries is increased in 002.

        I could reproduce the test failure in 10 runs without the patch. No failure in 100 runs with the patch applied.

        The failure of TestReplicationPolicyConsiderLoad was already fixed by HDFS-9597. Other tests are flaky regardless of the patch and succeeded on my local environment.

        +1 for the patch. I had an environment that was able to repro this test failure consistently. After applying the patch, I could no longer repro the failure. I have committed this to trunk. Masatake Iwasaki, thank you!
