Component/s: (was: security)
> Add capability in hadoop-client to automatically login from a client/service
> keytab
> -----------------------------------------------------------------------------------
>
> Key: HADOOP-16996
> URL: https://issues.apache.org/jira/browse/HADOOP-16996
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 2.0.0-alpha
> Reporter: Maziar Mirzazad
> Priority: Minor
> Fix For: 2.9.2
>
>
> With current hadoop client implementation, every single service need to add
> UGI.loginFromKeyTab() before doing HDFS or M/R API calls.
> To avoid that, we are proposing adding Keytab based login to hadoop client
> library for Kerberized clusters with configurable default paths for Keytabs.
> This improvement should avoid extra login tries in case a valid TGT is
> available.
