Eli Reisman commented on GIRAPH-258:
------------------------------------
All of the code is copied over from the GiraphMapper impl where the generics
were checked after the job was already running, test code didn't change, just
added the validator to it. I will remove check style comments. Those were the
pre-existing tests as well, and they work so I left them alone. I can change
the unchecked exceptions to fail() calls in the tests (that never made any
sense but I figured it was a separate issue) further (very reasonable) fixes to
the existing code I stole/moved might deserve its own JIRA.
Fixing now...

> Currently if one submits a job with a vertex and inputformat types that are
> not compatible the job only fails during runtime. Since we know the types at
> submission time, we can check this before submitting and fail then.
