--------------------------------------------
All the results above are generated using IntelliJ. I will try running the
tests with maven directly.
> Ozone: MiniOzoneCluster uses 400+ threads

> Key: HDFS-12163
> URL: https://issues.apache.org/jira/browse/HDFS-12163
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ozone, test
> Reporter: Tsz Wo Nicholas Sze
> Attachments: TestOzoneThreadCount20170719.patch
>
>
> Checked the number of active threads used in MiniOzoneCluster with various
> settings:
> - Local handlers
> - Distributed handlers
> - Ratis-Netty
> - Ratis-gRPC
> The results are similar for all the settings. It uses 400+ threads for an
> 1-datanode MiniOzoneCluster.
> Moreover, there is a thread leak -- a number of the threads do not shutdown
> after the test is finished. Therefore, when tests run consecutively, the
> later tests use more threads.
> Will post the details in comments.
