Without caching, each action is recomputed. So assuming rdd2 and rdd3
result in separate actions answer is yes.

I am having a similar problem:
I have a large dataset in HDFS and (for a few possible reason including a
filter operation, and some of my computation nodes simply not being hdfs
datanodes) have a large skew on my RDD blocks: the master node always has
the most, while the worker nodes have few... (
Are you directly caching files from Hadoop or are you doing some
transformation on them first? If you are doing a groupBy or some type of
transformation, then you could be causing data skew that way.
