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)
