Subject [jira] [Updated] (HADOOP-8852) Remove DelegationTokenRenewer
Date Fri, 05 Oct 2012 00:59:48 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-8852?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karthik Kambatla updated HADOOP-8852:
-------------------------------------

    Description: 
Update 2:
DelegationTokenRenewer is not required. The filesystems that are using it already have Krb
tickets and do not need tokens. Remove DelegationTokenRenewer and all the related logic from
WebHdfs and Hftp filesystems.

Update1:
DelegationTokenRenewer should be Singleton - the instance and renewer threads should be created/started
lazily. The filesystems using the renewer shouldn't need to explicity start/stop the renewer,
and only register/de-register for token renewal.

Original issue:
HftpFileSystem and WebHdfsFileSystem should stop the DelegationTokenRenewer thread when they
are closed.
