| |
| `SHOW` displays the current settings of HAWQ system configuration parameters. These parameters can be set using the `SET` statement, or by editing the `hawq-site.xml` configuration file of the HAWQ master. Note that some parameters viewable by `SHOW` are read-only — their values can be viewed but not set. See [About Server Configuration Parameters](../guc/guc_config.html#topic1). |
