/**
 * Configuration class for the HdfsSink. Delegates to a {@link DataStoreWriterFactoryBean} for
 * creating the writer used by the sink.
 * <p/>
 * The configuration contains the property 'fsUri' to configure a connection to HDFS as well as the
 * additional properties for the sink like directory, fileName, codec etc. You can also use the
 * standard 'spring.hadoop.fsUri' property for specifying the HDFS connection.
