Recall this was the error
21/03/18 16:53:38 ERROR org.apache.spark.scheduler.AsyncEventQueue:
Listener EventLoggingListener threw an exception
java.util.ConcurrentModificationException
at java.util.Hashtable$Enumerator.next(Hashtable.java:1387)
I resolved this error message by setting:
spark.conf.set("spark.eventLog.enabled", "false")
This happens when Spark writes to Google BigQuery table. The error is not a
show stopper
There is also a recent reference to event logging listener exception in
this jira
