---------------------------------
Summary: Spark event logs are huge compared to 1.5.2
Key: SPARK-19316
URL: https://issues.apache.org/jira/browse/SPARK-19316
Project: Spark
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Jisoo Kim
I have a Spark application with many tasks (more than 40k). The event logs for
such application used to be around 2g when I was using Spark 1.5.2 standalone
cluster. Now that I am using Spark 2.0 with Mesos, the size of the event log of
such application drastically increased from 2g to 60g with a similar number of
tasks. This is affecting Spark History Server since it is having trouble
reading such huge event log. I wonder the increase in a size of an event log is
expected in Spark 2.0.
