----------------------------------

             Summary: git diff --dirstat can miss sql changes and not run Hive tests
                 Key: SPARK-2747
                 URL: https://issues.apache.org/jira/browse/SPARK-2747
             Project: Spark
          Issue Type: Bug
          Components: Build
            Reporter: Reynold Xin
            Assignee: Reynold Xin
            Priority: Critical


dev/run-tests use "git diff --dirstat master" to check whether sql is changed. However, --dirstat won't show sql if sql's change is negligible (e.g. 1k loc change in core, and only 1 loc change in hive).

We should use "git diff --name-only master" instead.
