Subject Problems with Spark (Lost executor error)
Date Sun, 19 Jan 2014 12:08:30 GMT
Hello,

I am trying to read in a 20GB file from an S3 bucket. I have verified I can
read small files from my cluster. The cluster itself has 15 slaves and a
master, each slave has 16GB of RAM, the machines are Amazon m1.xlarge
instances.

All I am doing is below, however a minute into execution I get the ERROR
and the subsequent WARNings. Anyone have any ideas what is going on? Why is
this so difficult? ;)

Thanks!
Ognen
