> 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.
