Tsz Wo Nicholas Sze commented on HDFS-11948: -------------------------------------------- > Also in the profiler, I see around 2025 threads being launched for this > single test. Thought you might be interested in that. [~anu], I just have finished some testing and filed HDFS-12163. It turns out that an 1-datanode MiniOzoneCluster uses 400+ threads for both Ratis and non-Ratis settings. Also, there is a thread leak problem -- some threads used in earlier tests are leaked to later tests. The thread leak explains why there are around 2025 threads showed in the profiler. TestRatisManager uses 5 datanodes. It only uses a similar number of threads as other 5-datanode cases showed in [this comment|https://issues.apache.org/jira/browse/HDFS-12163?focusedCommentId=16093848&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16093848] - testTestRatisManagerNetty | (NETTY,5) | init | 6 | | (NETTY,5) | MiniOzoneCluster | 598 | | (NETTY,5) | ready | 598 | | (NETTY,5) | create RatisCluster | 690 | | (NETTY,5) | close RatisCluster | 722 | | (NETTY,5) | update RatisCluster | 807 | | (NETTY,5) | shutdown | 438 | | (NETTY,5) | sleep | 143 | - testTestRatisManagerGrpc | (GRPC,5) | init | 6 | | (GRPC,5) | MiniOzoneCluster | 600 | | (GRPC,5) | ready | 600 | | (GRPC,5) | create RatisCluster | 621 | | (GRPC,5) | close RatisCluster | 623 | | (GRPC,5) | update RatisCluster | 633 | | (GRPC,5) | shutdown | 257 | | (GRPC,5) | sleep | 137 | > Ozone: change TestRatisManager to check cluster with data > --------------------------------------------------------- > > Key: HDFS-11948 > URL: https://issues.apache.org/jira/browse/HDFS-11948 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ozone > Reporter: Tsz Wo Nicholas Sze > Assignee: Tsz Wo Nicholas Sze > Attachments: HDFS-11948-HDFS-7240.20170614.patch > > > TestRatisManager first creates multiple Ratis clusters.
