-------------------------------------
Summary: Spark-submit Jar URL loading fails on redirect
Key: SPARK-12825
URL: https://issues.apache.org/jira/browse/SPARK-12825
Project: Spark
Issue Type: Bug
Affects Versions: 1.6.0
Reporter: Alex Nederlof
Priority: Minor
When you use spark-submit, and pass the jar as a URL, it fails when the URL
redirects.
The log prints:
{code}
16/01/14 14:26:43 INFO Utils: Fetching http://myUrl/my.jar to
/opt/spark/spark-1.6.0-bin-hadoop2.6/work/driver-20160114142642-0010/fetchFileTemp8495494631100918254.tmp
{code}
However, that file doesn't exist, but a file called "redirect" is created, with
the appropriate content.
After that, the driver fails with
{code}
16/01/14 14:26:43 WARN Worker: Driver driver-20160114142642-0010 failed with
unrecoverable exception: java.lang.Exception: Did not see expected jar my.jar
in /opt/spark/spark-1.6.0-bin-hadoop2.6/work/driver-20160114142642-0010
{code}
Here's the related code:

My Scala chops aren't up to this challenge, otherwise I would have made a patch.
