-------------------------------------
Labels: authentication kerberos (was: )
> Support Kerberos authentication terminating at Accumulo
> -------------------------------------------------------
>
> Key: ACCUMULO-4306
> URL: https://issues.apache.org/jira/browse/ACCUMULO-4306
> Project: Accumulo
> Issue Type: Improvement
> Components: core
> Reporter: William Slacum
> Assignee: William Slacum
> Labels: authentication, kerberos
> Fix For: 1.8.0
>
>
> We currently support Kerberos authentication via SASL+GSSAPI. Due to an
> implementation detail, turning it on requires also enabling Kerberos for HDFS.
> This ticket proposes changing the implementation to avoid needing to turn on
> Kerberos authentication for HDFS, but still (optionally) using it. Mostly, I
> think this boils down to replacing uses of {{UserGroupInformation}} with
> {{Subject}} references. There are couple places (specifically around creating
> delegation tokens for use with a Kerberos-enabled Hadoop cluster) where
> `UserGroupInformation` may need to stick around.
