---------------------------------
Summary: NN should require authenticated connections to cancel
tokens
Key: HDFS-4568
URL: https://issues.apache.org/jira/browse/HDFS-4568
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode, security
Affects Versions: 2.0.0-alpha, 0.23.0, 3.0.0
Reporter: Daryn Sharp
The NN requires get/renew token operations to be securely authenticated - ie.
you can't use a token to get/renew a token. However, token cancelation is
allowed with a token, including using a token to cancel itself. Cancelation
should perform the same authentication checks as get/renew.
