Because of this reference, many FileSystem related objects (e.g. MetricsSystemImpl) cannot be garbage collected. Sometimes this causes OOM exception. Since the cleanup is done every 12 hours by default, we can simply recreate a FileSystem when we need to use it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
