[ https://issues.apache.org/jira/browse/HADOOP-18091?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Steve Loughran updated HADOOP-18091:
------------------------------------
Description:
{{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
