>
> Key: SPARK-5783
> URL: https://issues.apache.org/jira/browse/SPARK-5783
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.2.1
> Reporter: Ryan Williams
> Priority: Minor
>
> While investigating why some recent applications were not showing up in my
> History Server UI, I found error message blocks like this in the history
> server logs:
> {code}
> 15/02/12 18:51:55 ERROR scheduler.ReplayListenerBus: Exception in parsing
> Spark event log.
> java.lang.ClassCastException: org.json4s.JsonAST$JNothing$ cannot be cast to
> org.json4s.JsonAST$JObject

> org.apache.spark.util.JsonProtocol$.mapFromJson(JsonProtocol.scala:814)

> org.apache.spark.deploy.history.FsHistoryProvider$$anon$1.run(FsHistoryProvider.scala:84)
> 15/02/12 18:51:55 ERROR scheduler.ReplayListenerBus: Malformed line:
> {"Event":"SparkListenerExecutorAdded","Timestamp":1422897479154,"Executor
> ID":"12","Executor
> Info":{"Host":"demeter-csmaz11-1.demeter.hpc.mssm.edu","Total Cores":4}}
> {code}
> Turns out certain files had some malformed lines due to having been generated
> by a forked Spark with some WIP event-log functionality.
> It would be nice if the first line specified the file the error was found in,
> and the last line specified the line number.
