Kihwal Lee commented on HDFS-4887:
----------------------------------
I first tried using ExitUtil, but this test case and potentially others want to
stop ReplicationMonitor thread and the rest of the system to be up. If NN
exits, BlockManager is torn down and any subsequent checks by tests will race.
> 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
> Assignee: Kihwal Lee
> Attachments: HDFS-4887.patch, HDFS-4887.patch

> 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.
