sam created SPARK-5835:
--------------------------
Summary: 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
Affects Versions: 1.0.0
Reporter: sam
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.
