--------------------------------
Summary: Parameterize HCatMapReduceTest for testing against all
Hive storage formats
Key: HIVE-7286
URL: https://issues.apache.org/jira/browse/HIVE-7286
Project: Hive
Issue Type: Test
Components: HCatalog
Reporter: David Chen
Assignee: David Chen
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.
