Jason Lowe commented on YARN-6615:
----------------------------------
Thanks for backporting the patches! +1 for the branch-2.8/branch-2.7 patch,
lgtm. I'm not sure about the branch-2.6 patch since the findbugs warning
sounds ominous, as in "you _always_ have a bug if this is being flagged" type
of issue.
If there are no objections I'll commit the patches down through 2.7 tomorrow,
but I'm looking for someone with more knowledge on the findbugs warning to see
what needs to be done for 2.6 before that patch is committed.

> Key: YARN-6615
> URL: https://issues.apache.org/jira/browse/YARN-6615
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.8.0, 2.7.3, 2.6.5, 3.0.0-alpha2
> Reporter: Wilfred Spiegelenburg
> Assignee: Wilfred Spiegelenburg
> Attachments: YARN-6615.1.patch, YARN-6615-branch-2.6.1.patch,

> When an AM web request is redirected to the RM the query parameters are
> dropped from the web request.
> This happens for Spark as described in SPARK-20772.
> The repro steps are:
> - Start up the spark-shell in yarn mode and run a job
> - Try to access the job details through http://<fqdn>:4040/jobs/job?id=0
> - A HTTP ERROR 400 is thrown (requirement failed: missing id parameter)
> This works fine in local or standalone mode, but does not work on Yarn where
> the query parameter is dropped. If the UI filter
> org.apache.hadoop.yarn.server.webproxy.amfilter.AmIpFilter is removed from
> the config which shows that the problem is in the filter
