Fix Version/s: (was: 2.9.2)
> Add capability in hadoop-client to automatically login from a client/service keytab
> -----------------------------------------------------------------------------------
>
> Key: HADOOP-17005
> URL: https://issues.apache.org/jira/browse/HADOOP-17005
> Project: Hadoop Common
> Issue Type: Improvement
> Components: security
> Affects Versions: 2.0.0-alpha
> 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.
