[jira] [Created] (HDFS-4887) TestNNThroughputBenchmark exits abruptly

Kihwal Lee created HDFS-4887:
--------------------------------

             Summary: TestNNThroughputBenchmark exits abruptly
                 Key: HDFS-4887
                 URL: https://issues.apache.org/jira/browse/HDFS-4887
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: benchmarks, test
    Affects Versions: 3.0.0, 2.1.0-beta
            Reporter: Kihwal Lee


After HDFS-4840, TestNNThroughputBenchmark exits in the middle. This is because ReplicationMonitor is being stopped while NN is still running. 

This is only valid during testing. In normal cases, ReplicationMonitor thread runs all the time once started. In standby or safemode, it just skips calculating DN work. I think NNThroughputBenchmark needs to use ExitUtil to prevent termination, rather than modifying ReplicationMonitor.
