SPARK_WORKER_DIR and SPARK_LOCAL_DIR

[corrius <co...@gmail.com>]

Hello,

I have a 4 nodes spark cluster running on EC2 and it's running out of space
in disk. I'm running Spark 1.3.1.

I have mounted a second SSD disk in every instance on /tmp/spark and set
SPARK_LOCAL_DIRS and SPARK_WORKER_DIRS pointing to this folder:

set | grep SPARK
SPARK_LOCAL_DIRS=/tmp/spark
SPARK_WORKER_DIR=/tmp/spark

Once I start my cluster I can see that the Master get these variables and
put everything in /tmp/spark but the workers are still using /tmp/ to spill
data to the disk, what ends up filling the disk.

I also tried starting the workers with -d /tmp/spark and this only moves a
small file (app-...) from /opt/spark/work to my temp folder.

The folders and files I can still find in /tmp/ looks like:
spark-39fa5e41-3ce4-40e9-b2a7-8f3739db604e

I don't know if I am missing something, any help would be much appreciated.
