And this is happening in every job I run. It is not just one case. If I add
a forced repartitions it works fine, even better than before. But I run the

the initial
RDD conserve the same number of partitions, in 2.4 the number of partitions
reset to default.
So RDD1, the product of the first mapToPair, prints 5580 when
getPartitions() is called in 2.3.1, while prints 128 in 2.4.

The question now is why keyBy operation is using default parallelism
instead of the number of partition of the RDD created by the previous step
(5580).

It seems that in 5.20, a full instance is wasted with the driver only,
while it could also contain an executor.

Hi guys,
I use to run spark jobs in Aws emr.
Recently I switch from aws emr label 5.16 to 5.20 (which use Spark 2.4.0).

Prints an empty list.
This works alright running locally in my computer, but fail with no match

Thanks you very much,
