Vinod Kumar Vavilapalli updated MAPREDUCE-2970:
-----------------------------------------------
Status: Open (was: Patch Available)
- The ProtocolProviders don't work in isolation, they are all invoked one by
one to figure out which one is the correct framework in question. So none of
them can throw exceptions if they aren't configured.
- Don't think you got my comment about the test. Both the tests should be
combined into a single simple test which creates cluster objects with different
configurations and it should verify whether the right frameworks are used.
> Null Pointer Exception while submitting a Job, If mapreduce.framework.name
