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.
