Shixiong Zhu commented on SPARK-12825:
--------------------------------------
Is "redirect" implemented with JavaScript, or 301/302 http code? If it's
JavaScript, obviously Spark doesn't support it.
> 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}

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