org.apache.hadoop.gateway.config.impl.GatewayConfigImpl
The configuration for the Gateway. The Gateway configuration variables are described in gateway-default.xml The Gateway specific configuration is split into two layers: 1. gateway-default.xml - All the configuration variables that the Gateway needs. These are the defaults that ship with the app and should only be changed be the app developers. 2. gateway-site.xml - The (possibly empty) configuration that the system administrator can set variables for their Hadoop cluster. To find the gateway configuration files the following process is used. First, if the GATEWAY_HOME system property contains a valid directory name, an attempt will be made to read the configuration files from that directory. Second, if the GATEWAY_HOME environment variable contains a valid directory name, an attempt will be made to read the configuration files from that directory. Third, an attempt will be made to load the configuration files from the directory specified via the "user.dir" system property. Fourth, an attempt will be made to load the configuration files from the classpath. Last, defaults will be used for all values will be used. If GATEWAY_HOME isn't set via either the system property or environment variable then a value for this will be defaulted. The default selected will be the directory that contained the last loaded configuration file that was not contained in a JAR. If no such configuration file is loaded the value of the "user.dir" system property will be used as the value of GATEWAY_HOME. This is important to consider for any relative file names as they will be resolved relative to the value of GATEWAY_HOME. One such relative value is the name of the directory containing cluster topologies. This value default to "clusters".
