> 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.
