----------------------------------
Summary: Separate PXF system parameters from user configurable
visible parameters
Key: HAWQ-1581
URL: https://issues.apache.org/jira/browse/HAWQ-1581
Project: Apache HAWQ
Issue Type: Bug
Components: PXF
Reporter: Shivram Mani
Assignee: Ed Espino
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.
