Subject [jira] [Commented] (SPARK-17649) Log how many Spark events got dropped in LiveListenerBus
Date Wed, 28 Sep 2016 17:27:21 GMT

    [ https://issues.apache.org/jira/browse/SPARK-17649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15530301#comment-15530301

Shixiong Zhu commented on SPARK-17649:
--------------------------------------

My motivation of logging the dropped events is for helping find out a reasonable queue size.
Not sue if more stat information is helpful. You cannot drop only some types of messages.
