Driver fail with out of memory exception

[richiesgr <ri...@gmail.com>]

Hi

I've written a job (I think not very complicated only 1 reduceByKey) the
driver JVM always hang with OOM killing the worker of course. How can I know
what is running on the driver and what is running on the worker how to debug
the memory problem.
I've already used --driver-memory 4g params to give more memory ut nothing
help it always fail

Thanks

Try increasing the number of partitions while doing a reduceByKey()
<http://spark.apache.org/docs/latest/api/scala/index.html#org.apache.spark.api.java.JavaPairRDD>

Thanks
