Reynold Xin created SPARK-2747:
----------------------------------
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.
