Hey, I submitted this issue to Spark https://issues.apache.org/jira/browse/SPARK-13909
But I think it is rather a Zeppelin issue because it came with upgrade to current Zeppelin master version. It seems to be happening even on Spark 1.5.x ... Any idea what might be wrong? Simply any kind of DISK_ONLY leads to OOME ... I have a really simple single-node setup.
