Description

Few PRs failed on Spark 1.x profiles \w Scala 2.10 on DependencyResolverTest.testLoad loading spark-csv_2.10

I. DependencyResolverTest.testLoad \w spark-csv

• PR #1689, logs
• PR #1734, logs
• PR #1538, all Scala 2.11 profiles + Scala 2.10 as well

II. DepInterpreterTest.testDefault

• PR #1538, all Scala 2.11 profiles + Scala 2.10 as well
• PR #1689, Scala 2.10 profiles failure logs

Results :

Tests in error: 
  DepInterpreterTest.testDefault:96 » NullPointer

Tests run: 24, Failures: 0, Errors: 1, Skipped: 0

III. SparkParagraphIT.testDep

• PR #1538
• PR #1477, logs

Failed tests: 
  SparkParagraphIT.testDep:234 First paragraph from SparkParagraphIT of testDep status: 
Expected: "FINISHED"
     but: was "ERROR"

Tests in error: 
  ZeppelinIT.testSparkInterpreterDependencyLoading:234->AbstractZeppelinIT.waitForParagraph:70->AbstractZeppelinIT.pollingWait:96 » Timeout

Tests run: 18, Failures: 1, Errors: 1, Skipped: 0

It might be actually an expected behavior, as profiles \w *Scala 2.11* do fail tests on fetching *Scala 2.10* artefacts
