Hector Sandoval Chaverri updated HADOOP-18264:
----------------------------------------------
Priority: Minor (was: Major)
> ZKDelegationTokenSecretManager should handle duplicate Token sequenceNums
> -------------------------------------------------------------------------
>
> Key: HADOOP-18264
> URL: https://issues.apache.org/jira/browse/HADOOP-18264
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Reporter: Hector Sandoval Chaverri
> Priority: Minor
>
> The ZKDelegationTokenSecretManager relies on the TokenIdentifier
> sequenceNumber to identify each Token in the ZK Store. It's possible for
> multiple TokenIdentifiers to share the same sequenceNumber, as this is an int
> that can overflow.
> The AbstractDelegationTokenSecretManager uses a Map<TokenIdent,
> DelegationTokenInformation> so all properties in the TokenIdentifier must
> match. ZKDelegationTokenSecretManager should follow the same logic.
