> Currently, HCatMapReduceTest, which is extended by the following test suites:
>  * TestHCatDynamicPartitioned
>  * TestHCatNonPartitioned
>  * TestHCatPartitioned
>  * TestHCatExternalDynamicPartitioned
>  * TestHCatExternalNonPartitioned
>  * TestHCatExternalPartitioned
>  * TestHCatMutableDynamicPartitioned
>  * TestHCatMutableNonPartitioned
>  * TestHCatMutablePartitioned
> These tests run against RCFile. Currently, only TestHCatDynamicPartitioned is run against
any other storage format (ORC).
> Ideally, HCatalog should be tested against all storage formats supported by Hive. The
easiest way to accomplish this is to turn HCatMapReduceTest into a parameterized test fixture
that enumerates all Hive storage formats. Until HIVE-5976 is implemented, we would need to
manually create the mapping of SerDe to InputFormat and OutputFormat. This way, we can explicitly
keep track of which storage formats currently work with HCatalog or which ones are untested
or have test failures. The test fixture should also use Reflection to find all classes in
the classpath that implements the SerDe interface and raise a failure if any of them are not
enumerated.
