Alex Nederlof commented on SPARK-12825:
---------------------------------------
It's a `307 temporary redirect` response code, returned by Nexus.
The full command was
{code}
spark-submit --master spark://spark.ourserver.com:6066 --deploy-mode cluster
--class me.our.SparkJob --executor-memory 4g --driver-memory 4g
"http://our.nexus.repo/service/local/artifact/maven/redirect?r=snapshots&g=me.magnet&a=sparkjob&v=LATEST";
{code}
In curl you'd see
{code}
[alex in ~]$ curl -v
"http://our.nexus.repo/service/local/artifact/maven/redirect?r=snapshots&g=me.magnet&a=sparkjob&v=LATEST";

> 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

> {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

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