Method parameters in org.apache.hadoop.mapreduce.lib.db with type arguments of type DBWritable

static void	DBInputFormat.setInput(Job job, Class<? extends DBWritable> inputClass, String inputQuery, String inputCountQuery) Initializes the map-part of the job with the appropriate input settings.
static void	DataDrivenDBInputFormat.setInput(Job job, Class<? extends DBWritable> inputClass, String inputQuery, String inputBoundingQuery) setInput() takes a custom query and a separate "bounding query" to use instead of the custom "count query" used by DBInputFormat.
static void	DBInputFormat.setInput(Job job, Class<? extends DBWritable> inputClass, String tableName, String conditions, String orderBy, String... fieldNames) Initializes the map-part of the job with the appropriate input settings.
static void	DataDrivenDBInputFormat.setInput(Job job, Class<? extends DBWritable> inputClass, String tableName, String conditions, String splitBy, String... fieldNames) Note that the "orderBy" column is called the "splitBy" in this version.
void	DBConfiguration.setInputClass(Class<? extends DBWritable> inputClass)
