------------------------------------
Summary: Events being dropped at an alarming rate due to hsync
being slow for eventLogging
Key: SPARK-24787
URL: https://issues.apache.org/jira/browse/SPARK-24787
Project: Spark
Issue Type: Bug
Components: Spark Core, Web UI
Affects Versions: 2.3.1, 2.3.0
Reporter: Sanket Reddy
[https://github.com/apache/spark/pull/16924/files] updates the length of the
inprogress files allowing history server being responsive.
Although we have a production job that has 60000 tasks per stage and due to
hsync being slow it starts dropping events and the history server has wrong
stats due to events being dropped.
A viable solution is not to make it sync very frequently or make it
configurable.
