- Method Detail
  - getConfiguration
```
org.apache.hadoop.conf.Configuration getConfiguration()
```
    Returns the Configuration object used by this instance.
    The reference returned is not a copy, so any change made to it will affect this instance.
  - getRegionLocator
```
AsyncTableRegionLocator getRegionLocator(TableName tableName)
```
    Retrieve a AsyncRegionLocator implementation to inspect region information on a table. The returned AsyncRegionLocator is not thread-safe, so a new instance should be created for each using thread. This is a lightweight operation. Pooling or caching of the returned AsyncRegionLocator is neither required nor desired.
    
    Parameters:
    
    tableName - Name of the table who's region is to be examined
    
    Returns:
    
    An AsyncRegionLocator instance
  - getRawTable
```
default RawAsyncTable getRawTable(TableName tableName)
```
    Retrieve an RawAsyncTable implementation for accessing a table.
    The returned instance will use default configs. Use getRawTableBuilder(TableName) if you want to customize some configs.
    This method no longer checks table existence. An exception will be thrown if the table does not exist only when the first operation is attempted.
    
    Parameters:
    
    tableName - the name of the table
    
    Returns:
    
    an RawAsyncTable to use for interactions with this table
    
    See Also:
    
    getRawTableBuilder(TableName)
  - getRawTableBuilder
```
AsyncTableBuilder<RawAsyncTable> getRawTableBuilder(TableName tableName)
```
    Returns an AsyncTableBuilder for creating RawAsyncTable.
    This method no longer checks table existence. An exception will be thrown if the table does not exist only when the first operation is attempted.
    
    Parameters:
    
    tableName - the name of the table
  - getTable
```
default AsyncTable getTable(TableName tableName,
                            ExecutorService pool)
```
    Retrieve an AsyncTable implementation for accessing a table.
    This method no longer checks table existence. An exception will be thrown if the table does not exist only when the first operation is attempted.
    
    Parameters:
    
    tableName - the name of the table
    
    pool - the thread pool to use for executing callback
    
    Returns:
    
    an AsyncTable to use for interactions with this table
  - getTableBuilder
```
AsyncTableBuilder<AsyncTable> getTableBuilder(TableName tableName,
                                              ExecutorService pool)
```
    Returns an AsyncTableBuilder for creating AsyncTable.
    This method no longer checks table existence. An exception will be thrown if the table does not exist only when the first operation is attempted.
    
    Parameters:
    
    tableName - the name of the table
    
    pool - the thread pool to use for executing callback
  - getAdmin
```
default AsyncAdmin getAdmin()
```
    Retrieve an AsyncAdmin implementation to administer an HBase cluster.
    The returned instance will use default configs. Use getAdminBuilder() if you want to customize some configs.
    The admin operation's returned CompletableFuture will be finished directly in the rpc framework's callback thread, so typically you should not do any time consuming work inside these methods.
    
    Returns:
    
    an AsyncAdmin instance for cluster administration
  - getAdminBuilder
```
AsyncAdminBuilder<RawAsyncHBaseAdmin> getAdminBuilder()
```
    Returns an AsyncAdminBuilder for creating AsyncAdmin.
    The admin operation's returned CompletableFuture will be finished directly in the rpc framework's callback thread, so typically you should not do any time consuming work inside these methods.
  - getAdmin
```
default AsyncAdmin getAdmin(ExecutorService pool)
```
    Retrieve an AsyncAdmin implementation to administer an HBase cluster.
    The returned instance will use default configs. Use getAdminBuilder(ExecutorService) if you want to customize some configs.
    
    Parameters:
    
    pool - the thread pool to use for executing callback
    
    Returns:
    
    an AsyncAdmin instance for cluster administration
  - getAdminBuilder
```
AsyncAdminBuilder<AsyncHBaseAdmin> getAdminBuilder(ExecutorService pool)
```
    Returns an AsyncAdminBuilder for creating AsyncAdmin.
    
    Parameters:
    
    pool - the thread pool to use for executing callback
