Steve Loughran resolved AMBARI-21665.
-------------------------------------
Resolution: Won't Fix
> shaded AWS SDK in Hadoop JARs slowing ambari view loading
> ---------------------------------------------------------
>
> Key: AMBARI-21665
> URL: https://issues.apache.org/jira/browse/AMBARI-21665
> Project: Ambari
> Issue Type: Bug
> Components: ambari-views
> Reporter: Steve Loughran
> Priority: Major
>
> HADOOP-14040 moved Hadoop to using a fully shaded aws SDK JAR. While this
> addresses classpath grief downstream (jackson &c), apparently it hurts ambari
> view startup.
> Why? There's now a very large aws JAR in web-inf/classes which Jetty scans
> looking for @servlet tags of some form or other, which takes a few seconds.
> I'm willing to help fix this with whatever settings we can do to tell Jetty
> to stop this, as we aren't going to move back onto the older AWS SDKs:
> they're too much trouble.
