------------------------------------
Summary: Add spark-submit option for user to override ivy settings
used to resolve packages/artifacts
Key: SPARK-17568
URL: https://issues.apache.org/jira/browse/SPARK-17568
Project: Spark
Issue Type: Improvement
Components: Deploy, Spark Core
Reporter: Bryan Cutler
The {{--packages}} option to {{spark-submit}} uses Ivy to map Maven coordinates
to package jars. Currently, the IvySettings are hard-coded with Maven Central
as the last repository in the chain of resolvers.
At IBM, we have heard from several enterprise clients that are frustrated with
lack of control over their local Spark installations. These clients want to
ensure that certain artifacts can be excluded or patched due to security or
license issues. For example, a package may use a vulnerable SSL protocol; or a
package may link against an AGPL library written by a litigious competitor.
While additional repositories and exclusions can be added on the spark-submit
command line, this falls short of what is needed. With Maven Central always as
a fall-back repository, it is difficult to ensure only approved artifacts are
used and it is often the exclusions that site admins are not aware of that can
cause problems. Also, known exclusions are better handled through a centralized
managed repository rather than as command line arguments.
To resolve these issues, we propose the following change: allow the user to
specify an Ivy Settings XML file to pass in as an optional argument to
{{spark-submit}} (or specify in a config file) to define alternate repositories
used to resolve artifacts instead of the hard-coded defaults. The use case for
this would be to define a managed repository (such as Nexus) in the settings
file so that all requests for artifacts go through one location only.
Example usage:
{noformat}
$SPARK_HOME/bin/spark-submit --conf spark.ivy.settings=/path/to/ivysettings.xml
myapp.jar
{noformat}
