If caller wants to add config parameters from a file, the path to the conf file can be passed like this: -c <path-to-conf>. The file is presumed to have the Configuration file xml format and is added as a new Resource to the current Configuration. Use this mechanism to set Configuration such as what ClusterManager to use, etc. Here is an example file you might references that sets an alternate ClusterManager: {code} <?xml version="1.0" encoding="UTF-8"?> hbase.it.clustermanager.class org.apache.hadoop.hbase.MyCustomClusterManager {code} NOTE: The code searches for the file name passed on the CLASSPATH! Passing the path to a file will not work! Add the file to the CLASSPATH and then pass the filename as the '-c' arg.

Throws:

Exception
