Andrew Or created SPARK-13055: --------------------------------- Summary: SQLHistoryListener throws ClassCastException Key: SPARK-13055 URL: https://issues.apache.org/jira/browse/SPARK-13055 Project: Spark Issue Type: Bug Components: Spark Core Affects Versions: 1.5.0 Reporter: Andrew Or Assignee: Andrew Or
{code} 16/01/27 18:46:28 ERROR ReplayListenerBus: Listener SQLHistoryListener threw an exception java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long at scala.runtime.BoxesRunTime.unboxToLong(BoxesRunTime.java:110) at org.apache.spark.sql.execution.ui.SQLHistoryListener$$anonfun$onTaskEnd$1$$anonfun$5.apply(SQLListener.scala:334) at org.apache.spark.sql.execution.ui.SQLHistoryListener$$anonfun$onTaskEnd$1$$anonfun$5.apply(SQLListener.scala:334) at scala.Option.map(Option.scala:145) at org.apache.spark.sql.execution.ui.SQLHistoryListener$$anonfun$onTaskEnd$1.apply(SQLListener.scala:334) at org.apache.spark.sql.execution.ui.SQLHistoryListener$$anonfun$onTaskEnd$1.apply(SQLListener.scala:332) {code} SQLHistoryListener listens on SparkListenerTaskEnd events, which contain non-SQL accumulators as well. We try to cast all accumulators we encounter to Long, resulting in an error like this one. Note: this was a problem even before internal accumulators were introduced. If the task used a user accumulator of a type other than Long, we would still see this. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
