I am having similar issues with much smaller data sets. I am using spark
EC2 scripts to launch clusters, but I almost always end up with straggling
executors that take over a node's CPU and memory and end up never finishing.

Hi Reynold,
Nice! What spark configuration parameters did you use to get your job to
run successfully on a large dataset? My job is failing on 1TB of input data
(uncompressed) on a 4-node cluster (64GB memory per node). No OutOfMemory
errors just lost executors.
Thanks,
Soila

I'm not really at liberty to discuss details of the job. It involves some
expensive aggregated statistics, and took 10 hours to complete (mostly
bottlenecked by network io).

Reynold,
How complex was that job (I guess in terms of number of transforms and
actions) and how long did that take to process?

Actually we just ran a job with 70TB+ compressed data on 28 worker
nodes -
I didn't count the size of the uncompressed data, but I am guessing it
is
somewhere between 200TB to 700TB.

All,
What is the largest input data set y'all have come across that has
been
successfully processed in production using spark. Ball park?
