Alastair "Bell" Turner updated HAWQ-1036:
-----------------------------------------
Component/s: Security
PXF
> Support user impersonation in HAWQ
> ----------------------------------
>
> Key: HAWQ-1036
> URL: https://issues.apache.org/jira/browse/HAWQ-1036
> Project: Apache HAWQ
> Issue Type: New Feature
> Components: PXF, Security
> Reporter: Alastair "Bell" Turner
> Assignee: Lei Chang
> Attachments: HAWQ_Impersonation_rationale.txt
>
>
> 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...
