     [ https://issues.apache.org/jira/browse/SPARK-11214?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hans Fischer closed SPARK-11214.
--------------------------------
    Resolution: Fixed

Update: The problem only occur when you require a lot of ram. 30g or less will be fine. That was my learning.
