Grant Henke created KUDU-3287: --------------------------------- Summary: Threads can linger for some time after calling close on the Java KuduClient Key: KUDU-3287 URL: https://issues.apache.org/jira/browse/KUDU-3287 Project: Kudu Issue Type: Bug Affects Versions: 1.14.0, 1.13.0, 1.12.0 Reporter: Grant Henke Assignee: Grant Henke
After the upgrade to Netty 4 in Kudu 1.12 the close/shutdown behavior of the Java client changed where threads and resources could linger for some time after the call to close() returned. This looks the be because `bootstrap.config().group().shutdownGracefully` is called with the default of 15s and returns asynchronously. Additionally, the default ExecutorService was not shutdown on close. -- This message was sent by Atlassian Jira (v8.3.4#803005)
