Jia Fan created HADOOP-19049: -------------------------------- Summary: Class loader leak caused by StatisticsDataReferenceCleaner thread Key: HADOOP-19049 URL: https://issues.apache.org/jira/browse/HADOOP-19049 Project: Hadoop Common Issue Type: Bug Components: common Affects Versions: 3.3.6 Reporter: Jia Fan
The "org.apache.hadoop.fs.FileSystem$Statistics$StatisticsDataReferenceCleaner" daemon thread was created by FileSystem. This is fine if the thread's context class loader is the system class loader, but it's bad if the context class loader is a custom class loader. The reference held by this daemon thread means that the class loader can never become eligible for GC. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
