Grzegorz Dubicki edited comment on SPARK-3185 at 6/4/15 10:50 AM: ------------------------------------------------------------------ (EDITED) Sorry for the mess I made here. I have been using old code by mistak and that was the cause of my problem. Anyway I used this patch https://github.com/grzegorz-dubicki/spark-ec2/commit/a4a5a1713bac479f36aeccc1bd01ca02616e63bb to use Tachyon 0.5.0 instead of 0.4.1 and my cluster is being created without the exception mentioned in the original issue description. was (Author: grzegorz-dubicki): (EDITED) Sorry for the mess I made here.
