Aaron Kimball updated MAPREDUCE-1445:
-------------------------------------

    Attachment: MAPREDUCE-1445.patch

This patch takes the previous TestColumnTypes test and refactors it into an abstract class named ManagerCompatTest. This can be specialized on a per-ConnManager basis. The TestColumnTypes class is now the HSQLDB-based instantiation of ManagerCompatTest. This adds Oracle and MySQL-based tests as well.

The purpose of this patch is *not* to ensure that all databases import data in a byte-for-byte identical manner. Indeed, the datatypes supported by some databases are different than others. However, if a database supports some datatype, we must be able to verify that we can import it to HDFS in some recognizable representation. Therefore, there are a lot of hooks in ManagerCompatTest allowing subclasses to encode transformations from "canonical" expected results to the expected results particular to a database for some datatype.

> Sqoop's test suite is heavily biased toward testing with the HSQLDB embedded database. This issue proposes to refactor some tests into abstract classes which can be used as a basis for testing a variety of connection manager implementations, ensuring better cross-database compatibility coverage.
