User can simply skip calling collect and exception doesn't seem to be necessary.

> Currently there is no way, where user code can throw a specific Exception to notify the framework about skipping that record and move forward. 
> This can be implemented in map, reduce, combine, and output format (maybe) as well as input method.
> To get the skip behavior, the user needs to write code that throws these exceptions, so this would not change the systems default behavior.
