[HADOOP-10523] Hadoop services (such as RM, NN and JHS) throw confusing exception during token auto-cancelation

• Type: Bug

Description

When a user explicitly cancels the token, the system (such as RM, NN and JHS) also periodically tries to cancel the same token. During the second cancel (originated by RM/NN/JHS), Hadoop processes throw the following error/exception in the log file. Although the exception is harmless, it creates a lot of confusions and causes the dev to spend a lot of time to investigate.
This JIRA is to make sure if the token is available/not cancelled before attempting to cancel the token and finally replace this exception with proper warning message.
