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

Modifier and Type	Method	Description
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	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.
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	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.
void	DBConfiguration.setInputClass(Class<? extends DBWritable> inputClass)
