> 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

> 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.
