Subject [jira] [Created] (HADOOP-10523) Hadoop services (such as RM, NN and JHS) throw confusing exception during token auto-cancelation
Date Fri, 18 Apr 2014 23:18:22 GMT
Mohammad Kamrul Islam created HADOOP-10523:
----------------------------------------------

             Summary: Hadoop services (such as RM, NN and JHS) throw confusing exception during
token auto-cancelation 
                 Key: HADOOP-10523
                 URL: https://issues.apache.org/jira/browse/HADOOP-10523
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 2.3.0
            Reporter: Mohammad Kamrul Islam
            Assignee: Mohammad Kamrul Islam


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.
