* Abstract class representing a pluggable intermediate data format the Sqoop

* data. The data format should also be able to return the data as an object
* array - each array representing one row.
* <p/>
* Why a "native" internal format and then return text too?
* Imagine a connector that moves data from a system that stores data as a
* serialization format called FooFormat. If I also need the data to be
* written into HDFS as FooFormat, the additional cycles burnt in converting
* the FooFormat to text and back is useless - so plugging in an intermediate
* format that can store the data as FooFormat saves those cycles!
* <p/>
* Most fast access mechanisms, like mysqldump or pgsqldump write the data
* out as CSV, and most often the destination data is also represented as CSV
* - so having a minimal CSV support is important, so we can easily pull the
* data out as text.
* <p/>
* Any conversion to the final format from the native or text format is to be
* done by the connector or OutputFormat classes.
