-------------------------------------------------
Summary: 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
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.
