>             Project: Apache HAWQ
>          Issue Type: Bug
>          Components: PXF
>            Reporter: Shivram Mani
>            Assignee: Shivram Mani
>            Priority: Major
>             Fix For:
> We need to modify our system such that user configurable options are kept 
> distinct form the internal parameters. The custom parameters are configured 
> in the {{LOCATION}} section of the external table DDL, is exposed to PXF 
> server as {{X-GP-<param_name>}}.
> {{X-GP-USER}} is an internal parameter used to set the user information. When 
> the DDL has a custom parameter named {{user}} it ends up updating X-GP-USER 
> to also include the user configured in the DDL Location. This causes the JDBC 
> connector to fail.
> We will instead use \{X-GP-OPTIONS-} as the prefix for all user configurable 
> parameters to keep them isolated.
