> Project: Hadoop Common
> Issue Type: Bug

> Attachments: HADOOP-11482.1.patch, HADOOP-11482.2.patch
>
>
> Long Living clients of HDFS (For eg. OOZIE) use cached DFSClients which in
> turn use a cached KMSClientProvider to talk to KMS.
> Before an MR Job is run, the job client calls the
> {{DFClient.addDelegationTokens()}} method which calls
> {{addDelegationTokens()}} on the {{KMSClientProvider}} to get any delegation
> token associated to the user.
> Unfortunately, this call uses a cached
> {{DelegationTokenAuthenticationURL.Token}} instance which can cause the
> {{SignerSecretProvider}} implementation of the {{AuthenticationFilter}} at
> the KMS Server end to fail validation. Which results in the MR job itself
> failing.
