---------------------------------------------------------

this request has nothing to do with database objects privilege management or ranger integration.
Alastair‘s attached text file well elaborated on the implementation for this JIRA.

I'll make sure I describe that in the JIRA description as well.

I'll post a detailed discussion with Alastair before.

> 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...
