[jira] [Commented] (HADOOP-8852) DelegationTokenRenewer thread is not stopped when its filesystem is closed

    [ https://issues.apache.org/jira/browse/HADOOP-8852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13464120#comment-13464120 ] 

Karthik Kambatla commented on HADOOP-8852:
------------------------------------------

{{DelegationTokenRenewer}} fields in both filesystems are static fields. As stopping the thread corresponding to static field in close() does not seem like good practice, we should make them non-static.
