  - addHbaseResources
```
public static org.apache.hadoop.conf.Configuration addHbaseResources(org.apache.hadoop.conf.Configuration conf)
```
  - create
```
public static org.apache.hadoop.conf.Configuration create()
```
    Creates a Configuration with HBase resources
    
    Returns:
    a Configuration with HBase resources
  - create
```
public static org.apache.hadoop.conf.Configuration create(org.apache.hadoop.conf.Configuration that)
```
    Parameters:
    that - Configuration to clone.
    
    Returns:
    a Configuration created with the hbase-*.xml files plus the given configuration.
  - merge
```
public static void merge(org.apache.hadoop.conf.Configuration destConf,
         org.apache.hadoop.conf.Configuration srcConf)
```
    Merge two configurations.
    
    Parameters:
    destConf - the configuration that will be overwritten with items from the srcConf
    srcConf - the source configuration
  - isShowConfInServlet
```
public static boolean isShowConfInServlet()
```
    Returns:
    whether to show HBase Configuration in servlet
  - getInt
```
public static int getInt(org.apache.hadoop.conf.Configuration conf,
         String name,
         String deprecatedName,
         int defaultValue)
```
    Get the value of the name property as an int, possibly referring to the deprecated name of the configuration property. If no such property exists, the provided default value is returned, or if the specified value is not a valid int, then an error is thrown.
    
    Parameters:
    name - property name.
    deprecatedName - a deprecatedName for the property to use if non-deprecated name is not used
    defaultValue - default value.
    
    Returns:
    property value as an int, or defaultValue.
    
    Throws:
    
    NumberFormatException - when the value is invalid
  - getPassword
```
public static String getPassword(org.apache.hadoop.conf.Configuration conf,
                 String alias,
                 String defPass)
                          throws IOException
```
    Get the password from the Configuration instance using the getPassword method if it exists. If not, then fall back to the general get method for configuration elements.
    
    Parameters:
    conf - configuration instance for accessing the passwords
    alias - the name of the password element
    defPass - the default password
    
    Returns:
    String password or default password
    
    Throws:
    
    IOException
  - main
```
public static void main(String[] args)
                 throws Exception
```
    For debugging. Dump configurations to system output as xml format. Master and RS configurations can also be dumped using http services. e.g. "curl http://master:16010/dump"
    
    Throws:
    
    Exception
