> We need to ensure that MR failures on the server doesn't block further job submissions.

> First of all we should cover such situations with tests.
> 1) Test exceptions on all job stages (setup, map, reduce, combine, cleanup)
> 2) Test several exception types: 
> - Exceptions expected from Hadoop interface
> - Exceptions unexpected form Hadoop interface
> - Errors.
