Bryan Cutler commented on SPARK-12666:
--------------------------------------
This seems like it is more of an issue with SBT publishLocal, as it publishes
an ivy.xml file without a "default" conf. Like this, for example
{noformat}
<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra";>
...
<configurations>
<conf name="compile" visibility="public" description=""/>
<conf name="runtime" visibility="public" description=""
extends="compile"/>
<conf name="test" visibility="public" description=""
extends="runtime"/>
<conf name="provided" visibility="public" description=""/>
<conf name="optional" visibility="public" description=""/>
<conf name="it" visibility="public" description=""
extends="test"/>
<conf name="sources" visibility="public" description=""/>
<conf name="docs" visibility="public" description=""/>
<conf name="pom" visibility="public" description=""/>
</configurations>
...
{noformat}
If this file had a conf name="default", or if there were no confs defined an
implicit "default" would be used. But since it is missing, there is an error
when resolving. I think it's reasonable for Spark to expect a "default" conf
to exist, but we can make it a bit more robust to handle cases like this where
it doesn't exist. I'll post a PR for this.

> Key: SPARK-12666

> Project: Spark
> Issue Type: Bug
> Components: Spark Submit
> Affects Versions: 1.5.1, 1.6.0
> Reporter: Josh Rosen
>
> Symptom:
> I cloned the latest master of {{spark-redshift}}, then used {{sbt
> publishLocal}} to publish it to my Ivy cache. When I tried running
> {{./bin/spark-shell --packages
> com.databricks:spark-redshift_2.10:0.5.3-SNAPSHOT}} to load this dependency
> into {{spark-shell}}, I received the following cryptic error:
> {code}
> Exception in thread "main" java.lang.RuntimeException: [unresolved
> dependency: com.databricks#spark-redshift_2.10;0.5.3-SNAPSHOT: configuration
> not found in com.databricks#spark-redshift_2.10;0.5.3-SNAPSHOT: 'default'. It
> was required from org.apache.spark#spark-submit-parent;1.0 default]
> at
> org.apache.spark.deploy.SparkSubmitUtils$.resolveMavenCoordinates(SparkSubmit.scala:1009)
> at
> org.apache.spark.deploy.SparkSubmit$.prepareSubmitEnvironment(SparkSubmit.scala:286)
> at org.apache.spark.deploy.SparkSubmit$.submit(SparkSubmit.scala:153)
> at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:120)
> at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)
> {code}
> I think the problem here is that Spark is declaring a dependency on the
> spark-redshift artifact using the {{default}} Ivy configuration. Based on my
> admittedly limited understanding of Ivy, the default configuration will be
> the only configuration defined in an Ivy artifact if that artifact defines no
> other configurations. Thus, for Maven artifacts I think the default
> configuration will end up mapping to Maven's regular JAR dependency (i.e.
> Maven artifacts don't declare Ivy configurations so they implicitly have the
> {{default}} configuration) but for Ivy artifacts I think we can run into
> trouble when loading artifacts which explicitly define their own
> configurations, since those artifacts might not have a configuration named
> {{default}}.
> I spent a bit of time playing around with the SparkSubmit code to see if I
> could fix this but wasn't able to completely resolve the issue.
> /cc [~brkyvz] (ping me offline and I can walk you through the repo in person,
> if you'd like)
