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)`
