Aaron Davidson created SPARK-3029: ------------------------------------- Summary: Disable local execution of Spark jobs by default Key: SPARK-3029 URL: https://issues.apache.org/jira/browse/SPARK-3029 Project: Spark Issue Type: Improvement Reporter: Aaron Davidson Assignee: Aaron Davidson
Currently, local execution of Spark jobs is only used by take(), and it can be problematic as it can load a significant amount of data onto the driver. The worst case scenarios occur if the RDD is cached (guaranteed to load whole partition), has very large elements, or the partition is just large and we apply a filter with high selectivity or computational overhead. Additionally, jobs that run locally in this manner do not show up in the web UI, and are thus harder to track or understand what is occurring. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
