> Currently HAWQ executes all queries as the user running the HAWQ process or the user running the PXF process, not as the user who issued the query via ODBC/JDBC/... This restricts the options available for integrating with existing security defined in HDFS, Hive, etc.
> Impersonation provides an alternative Ranger integration (as discussed in HAWQ-256 ) for consistent security across HAWQ, HDFS, Hive...
