NoSuchElementException: key not found

Hi, I was working with a simple task (running locally). Just reading a file (35 mb) with about 200 features and making a random forest with 5 trees with 5 depth.  While saving the file with: predictions.select("VisitNumber", "probability")    .write.format("json") // tried different formats

Re: NoSuchElementException: key not found

I think I know what is going on! This probably a race condition in the DAGScheduler. I have added a JIRA for this. The fix is not trivial though. https://issues.apache.org/jira/browse/SPARK-2002 A not-so-good workaround for now would be not use coalesced RDD, which is avoids the race condition.

Re: NoSuchElementException: key not found

Hi Tathagata, Thanks for your help! By not using coalesced RDD, do you mean not repartitioning my Dstream? Thanks, Mike On Tue, Jun 3, 2014 at 12:03 PM, Tathagata Das tathagata.das1...@gmail.com wrote: I think I know what is going on! This probably a race condition in the DAGScheduler. I

Re: NoSuchElementException: key not found

I am not sure what DStream operations you are using, but some operation is internally creating CoalescedRDDs. That is causing the race condition. I might be able help if you can tell me what DStream operations you are using. TD On Tue, Jun 3, 2014 at 4:54 PM, Michael Chang m...@tellapart.com

NoSuchElementException: key not found

Hi all, Seeing a random exception kill my spark streaming job. Here's a stack trace: java.util.NoSuchElementException: key not found: 32855 at scala.collection.MapLike$class.default(MapLike.scala:228) at scala.collection.AbstractMap.default(Map.scala:58) at

Re: NoSuchElementException: key not found

Do you have the info level logs of the application? Can you grep the value 32855 to find any references to it? Also what version of the Spark are you using (so that I can match the stack trace, does not seem to match with Spark 1.0)? TD On Mon, Jun 2, 2014 at 3:27 PM, Michael Chang
