Description
Cascading supports Hadoop MR1 0.20.2. Thus I expect that it should work using CDH4 with it's MR1 component.
Running Cascading unit tests and they all pass except for the one that tests serialization.
I created a fork of cascading's code base to build against CDH4. It is available here: https://github.com/plaflamme/cascading (see cdh4 branch).
Running unit tests results in this:
...
:src:hadoop:test
Test cascading.tuple.hadoop.SerializedPipesPlatformTest FAILED
546 tests completed, 7 failures
