> 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
> Priority: Major
> Labels: pull-request-available
>
> 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.
