Spark 1.1-snapshot: java.io.FileNotFoundException from ShuffleMapTask

[npanj <ni...@gmail.com>]

Quite often I notice that shuffle file is missing thus FileNotFoundException
is throws.
Any idea why shuffle file will be missing ? Am I running low in memory?
(I am using latest code from master branch on yarn-hadoop-2.2)
