I believe this patch implements the original design goal: if a committer 
doesn't have a working path supplied by `getWorkingPath()` then it downgrades. 

It might be worthwhile doing a larger fault-injecting committer at some 
point.  have indirectly the ability to inject faults, but its a long way from 
the spark codebase, when really a thin shim is all that's needed. In 
particular, if a fault injecting ParquetOutputCommitter would test a big chunk 
of the codebase whose error handling codepaths are more likely to be tested in 
production than by jenkins. Are people interested (separate JIRA, obviously)

OK. LGTM. I think this anyway should issue warnings:

```
WARN org.apache.hadoop.mapreduce.lib.output.FileOutputCommitter: Output 
Path is null in setupJob()
WARN org.apache.hadoop.mapreduce.lib.output.FileOutputCommitter: Output 
Path is null in commitJob()
```

and I assume we prefer working permissively rather than failing fast. At 
least, it looks that's what `FileOutputCommitter` allows even if it skips 
moving the output.

Please make a followup if I misunderstood and anything is wrong. Will merge 
this one in few days.
