>
> Key: SPARK-25681
> URL: https://issues.apache.org/jira/browse/SPARK-25681
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes, Mesos, YARN
> Affects Versions: 2.5.0
> Reporter: Ilan Filonenko
> Priority: Major
> Labels: Hadoop, Kerberos
>
> Looking for a refactor to {{HadoopFSDelegationTokenProvider.}} Within the function {{obtainDelegationTokens()}}:
> This code-block:
> {code:java}
> val fetchCreds = fetchDelegationTokens(getTokenRenewer(hadoopConf),...)
> // Get the token renewal interval if it is not set. It will only be called once.
> if (tokenRenewalInterval == null) {
> tokenRenewalInterval = getTokenRenewalInterval(...)
> }{code}
> calls {{fetchDelegationTokens()}} twice since the {{tokenRenewalInterval}} will always be null upon creation of the {{TokenManager}} which I think is unnecessary in the case of Kubernetes (as you are creating 2 DTs when only one is needed.) Could this possibly be refactored to only call {{fetchDelegationTokens()}} once upon startup or to have a param to specify {{tokenRenewalInterval}}
