# Validate the Configuration File

You can use the `ValidateConfig` service action to check for errors in the configuration file.

NOTE: For the `ValidateConfig` action to validate a configuration section, Hadoop Connector must have previously read that configuration. In some cases, the configuration might be read when a task is run, rather than when the component starts up. In these cases, `ValidateConfig` reports any unread sections of the configuration file as unused.

To validate the configuration file

- Send the following action to Hadoop Connector:

      http://Host:ServicePort/action=ValidateConfig

  where:

  `Host` | is the host name or IP address of the machine where Hadoop Connector is installed.
  `ServicePort` | is the service port, as specified in the `[Service]` section of the configuration file.
