-------------------------------------------------------------
The file was confirmed to show up, although at the time I did not confirm permissions. Ran a test today and confirmed permissions were valid (assuming "-rw-r--r--" is valid).
Fair enough if yarn w/ non-HDFS is not supported. FWIW this test has passed since Spark 2.0.

> I have a set of scripts that run Spark with data in a networked file system. One of my unit tests to make sure things don't break between Spark releases is to simply run a word count (via org.apache.spark.examples.JavaWordCount) on a file in the networked file system. This test broke with Spark 2.2.0 when I use yarn to launch the job (using the spark standalone scheduler things still work). I'm currently using Hadoop 2.7.0. I get the following error:

> While debugging, I sat and watched the directory and did see that /p/lcratery/achu/testing/rawnetworkfs/test/1181015/node-0/spark/node-0/spark-292938be-7ae3-460f-aca7-294083ebb790/__spark_libs__695301535722158702.zip does show up at some point.
> Wondering if it's possible something racy was introduced. Nothing in the Spark 2.2.0 release notes suggests any type of configuration change that needs to be done.
> Thanks
