our experience is that unless you can benefit from spark features such as
co-partitioning that allow for more efficient execution that spark is
slightly slower for disk to disk.

Spark is much faster than Hadoop MapReduce even on disk
I believe the typical answer is that Spark is actually a bit slower.

Is it? I learned somewhere else that spark's speed is 5~10 times faster than
Hadoop MapReduce.

Hi,
I am frequently asked why spark is also much faster than Hadoop MapReduce on
disk (without the use of memory cache). I have no convencing answer for this
question, could you guys elaborate on this? Thanks!
