> Key: HADOOP-17005
> URL: https://issues.apache.org/jira/browse/HADOOP-17005
> Project: Hadoop Common
> Issue Type: Improvement
> Components: security
> Affects Versions: 3.2.1
> Reporter: Maziar Mirzazad
> Priority: Minor
>
> With existing Hadoop client implementation, client applications for services
> that are using kerberized clusters, need to handle Keytab based login in
> their code, before doing HDFS or M/R API calls.
> To avoid that, we are proposing adding Keytab based auto login to hadoop
> client library with configurable and default paths for Keytabs.
> This functionality helps new service owners as well as those transitioning
> from non-kerberized cluster to kerberized ones.
> Auto login, should avoid extra login attempts in case a valid TGT is already
> available.
