## <a id="topic1__section3"></a>Description
-The `hawq check` utility determines the platform on which you are running HAWQ and validates various platform-specific configuration settings as well as HAWQ and HDFS-specific configuration settings. In order to perform HAWQ configuration checks, make sure HAWQ has been already started and `hawq config` works. For HDFS checks, you should either set the HADOOP\_HOME environment variable or give the hadoop installation location using `--hadoop` option.
+The `hawq check` utility determines the platform on which you are running HAWQ and validates various platform-specific configuration settings as well as HAWQ and HDFS-specific configuration settings.

For HDFS checks, you should either set the HADOOP\_HOME environment variable or provide the hadoop installation location using `--hadoop` option.
-The `hawq check` utility can use a host file or a file previously created with the `--zipout `option to validate platform settings. If `GPCHECK_ERROR` displays, one or more validation checks failed. You can also use `hawq check` to gather and view platform settings on hosts without running validation checks. When running checks, `hawq check` compares your actual configuration setting with an expected value listed in a config file (`$GPHOME/etc/hawq check.cnf` by default). You must modify your configuration values for "mount.points" and "diskusage.monitor.mounts" to reflect the actual mount points you want to check, as a comma-separated list. Otherwise, the utility only checks the root directory, which may not be helpful.
