Sean Owen updated SPARK-5835:
-----------------------------
Component/s: Tests
Priority: Minor (was: Major)
You say you're not running in parallel but are you creating multiple
SparkContexts? then this is the same as
https://issues.apache.org/jira/browse/SPARK-2243
> Unit test causes java.io.FileNotFoundException on localhost for file
> "broadcast_1"
> ----------------------------------------------------------------------------------
>
> Key: SPARK-5835
> URL: https://issues.apache.org/jira/browse/SPARK-5835
> Project: Spark
> Issue Type: Bug
> Components: Tests
> Affects Versions: 1.0.0
> Reporter: sam
> Priority: Minor
>
> Note, I do not believe this is related to SPARK-2984 since I have speculative
> execution off (it's off by default in 1.0.0).
> I intermittently get the following stack trace in my unit tests. I'm using
> specs2 and I have "sequential" in the tests (so should not be bumping into
> each other), and also I have `parallelExecution in Test := false` in my
> `build.sbt`.
> This isn't a major showstopper, it just means our CI pipelines need some
> "retry" logic to workaround the erroring tests.
> [error] Could not run test my.test.Class: org.apache.spark.SparkException:
> Job aborted due to stage failure: Task 4.0:0 failed 1 times, most recent
> failure: Exception failure in TID 6 on host localhost:
> java.io.FileNotFoundException: http://blar.blar.blar.blar:59528/broadcast_1
