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)
