Singleton
[ https://issues.apache.org/jira/browse/HADOOP-8852?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Karthik Kambatla updated HADOOP-8852:
-------------------------------------
Description:
Updated description:
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.
was:HftpFileSystem and WebHdfsFileSystem should stop the DelegationTokenRenewer thread when they are closed.
Summary: DelegationTokenRenewer should be Singleton (was: DelegationTokenRenewer thread is not stopped when its filesystem is closed)
