             Summary: S3A auditing leaks memory through ThreadLocal references
                 Key: HADOOP-18091
                 URL: https://issues.apache.org/jira/browse/HADOOP-18091
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.3.2
            Reporter: Steve Loughran
            Assignee: Steve Loughran


{{ActiveAuditManagerS3A)) uses thread locals to map to active audit spans, which (because they are wrapped) include back reference to the audit manager instance and the config it was created with.

these *do not* get cleaned up when the FS instance is closed.

if you have a long lived process creating and destroying many FS instances, then memory gets used up. l
