Daniel Dai commented on PIG-3288:
---------------------------------
How about putting the counter logic in the StoreFunc? Seems your patch only
deals with PigTextInputFormat based StoreFunc. If we can push this to
StoreFunc, other StoreFunc can implement the same thing.
> Kill jobs if the number of output files is over a configurable limit

> 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.
