----------------------------------
I have do this similar https://github.com/apache/spark/pull/16803
> Customizable remote repository url for hive versions unit test
> --------------------------------------------------------------
>
> Key: SPARK-19836
> URL: https://issues.apache.org/jira/browse/SPARK-19836
> Project: Spark
> Issue Type: Bug
> Components: Tests
> Affects Versions: 2.1.0
> Reporter: Elek, Marton
> Labels: ivy, unittest
>
> When the VersionSuite test runs from sql/hive it downloads different versions
> from hive.
> Unfortunately the IsolatedClientClassloader (which is used by the
> VersionSuite) uses hardcoded fix repositories:
> {code}
> val classpath = quietly {
> SparkSubmitUtils.resolveMavenCoordinates(
> hiveArtifacts.mkString(","),
> SparkSubmitUtils.buildIvySettings(
> Some("http://www.datanucleus.org/downloads/maven2";),
> ivyPath),
> exclusions = version.exclusions)
> }
> {code}
> The problem is with the hard-coded repositories:
> 1. it's hard to run unit tests in an environment where only one internal
> maven repository is available (and central/datanucleus is not)
> 2. it's impossible to run unit tests against custom built hive/hadoop
> artifacts (which are not available from the central repository)
> VersionSuite has already a specific SPARK_VERSIONS_SUITE_IVY_PATH environment
> variable to define a custom local repository as ivy cache.
> I suggest to add an additional environment variable
> (SPARK_VERSIONS_SUITE_IVY_REPOSITORIES to the HiveClientBuilder.scala), to
> make it possible adding new remote repositories for testing the different
> hive versions.
