> I ran into a situation where a Pig job tried to create too many files on hdfs
> and overloaded NN. To prevent such events, it would be nice if we could set a
> upper limit on the number of files that a Pig job can create.
> In fact, Hive has a property called "hive.exec.max.created.files". The idea
> is that each mapper/reducer increases a counter every time when they create
> files. Then, MRLauncher periodically checks whether the number of created
> files so far has exceeded the upper limit. If so, we kill running jobs and
> exit.
