      Description

      We've seen several stacktraces and threads on the user mailing list where people are having issues with a FileNotFoundException stemming from an HDFS path containing _temporary.

      I (Andrew Ash) think this may be related to spark.speculation. I think the error condition might manifest in this circumstance:

      1) task T starts on a executor E1
      2) it takes a long time, so task T' is started on another executor E2
      3) T finishes in E1 so moves its data from _temporary to the final destination and deletes the _temporary directory during cleanup
      4) T' finishes in E2 and attempts to move its data from _temporary, but those files no longer exist! exception

      Some samples:

      I am running a Spark Streaming job that uses saveAsTextFiles to save results into hdfs files. However, it has an exception after 20 batches
      
      result-1406312340000/_temporary/0/task_201407251119_0000_m_000003 does not exist.
