There's a CircleCI commit tacked on the end of each which needs to be dropped before merge. 2.2 | [Branch|https://github.com/jonmeredith/cassandra/commits/CASSANDRA-15170-2.2] | [CircleCI|https://circleci.com/workflow-run/db122979-d47a-4d3a-a0e5-0cedef411a46] 3.0 | [Branch|https://github.com/jonmeredith/cassandra/commits/CASSANDRA-15170-3.0] | [CircleCI|https://circleci.com/workflow-run/370d6e4c-6ae8-4167-967a-a88e7b906582] 3.11 | [Branch|https://github.com/jonmeredith/cassandra/commits/CASSANDRA-15170-3.11] | [CircleCI|https://circleci.com/workflow-run/aecdc4ac-c267-435e-8d2e-4f238e02d9be] trunk | [Branch|https://github.com/jonmeredith/cassandra/commits/CASSANDRA-15170-trunk] | [CircleCI J8|https://circleci.com/workflow-run/eb1ad032-7b76-4aa2-a975-4ba6496bb74f] | [CircleCI J11|https://circleci.com/workflow-run/c8da2408-6caa-474c-894b-e41c029e2139] Thanks for all the effort reviewing/rereviewing. was (Author: jmeredithco): Apologies, messed up the 3.11 [CircleCI link|https://circleci.com/workflow-run/aecdc4ac-c267-435e-8d2e-4f238e02d9be] > Reduce the time needed to release in-JVM dtest cluster resources after close > ---------------------------------------------------------------------------- > > Key: CASSANDRA-15170 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15170 > Project: Cassandra > Issue Type: Improvement > Components: Test/dtest > Reporter: Jon Meredith > Assignee: Jon Meredith > Priority: Normal > > There are a few issues that slow the in-JVM dtests from reclaiming metaspace > once the cluster is closed. > IsolatedExecutor issues the shutdown on a SingleExecutorThreadPool, sometimes > this thread was still running 10s after the dtest cluster was closed. > Instead, switch to a ThreadPoolExecutor with a core pool size of 0 so that > the thread executing the class loader close executes sooner. > If an OutboundTcpConnection is waiting to connect() and the endpoint is not > answering, it has to wait for a timeout before it exits.
