> Key: HADOOP-13487
> URL: https://issues.apache.org/jira/browse/HADOOP-13487
> Project: Hadoop Common
> Issue Type: Bug
> Components: kms
> Affects Versions: 2.6.0
> Reporter: Alex Ivanov
> Assignee: Xiao Chen
> Attachments: HADOOP-13487.01.patch, HADOOP-13487.02.patch, HADOOP-13487.03.patch, HADOOP-13487.04.patch, HADOOP-13487.05.patch

> Configuration:
> CDH 5.5.1 (Hadoop 2.6+)
> KMS configured to store delegation tokens in Zookeeper
> DEBUG logging enabled in /etc/hadoop-kms/conf/kms-log4j.properties
> Findings:
> It seems to me delegation tokens never get cleaned up from Zookeeper past their renewal date. I can see in the logs that the removal thread is started with the expected interval:
> {code}
> 2016-08-11 08:15:24,511 INFO AbstractDelegationTokenSecretManager - Starting expired delegation token remover thread, tokenRemoverScanInterval=60 min(s)
> {code}
> However, I don't see any delegation token removals, indicated by the following log message:
> org.apache.hadoop.security.token.delegation.ZKDelegationTokenSecretManager --> removeStoredToken(TokenIdent ident), line 769 [CDH]
> {code}
> if (LOG.isDebugEnabled()) {
> LOG.debug("Removing ZKDTSMDelegationToken_"
> + ident.getSequenceNumber());
> }
> {code}
> Meanwhile, I see a lot of expired delegation tokens in Zookeeper that don't get cleaned up.
