   Hi @Z0ltrix.  I believe that Drill uses the native support for impersonation that is built into Hadoop when it impersonates to HDFS, Hive, HBase (and MapR-DB through whatever is built into that).  No other storage plugins support any impersonation yet.  Also there is no support for propagating a Kerberos authn context (a TGT I guess?) over the hop from Drill to the external data source.  But... we want it to be there!  We are in a planning phase and talking to security guys and we want to start coding on this in November.  Your input is very valuable so we'd like to keep checking in with you as we go.
