Dongjoon Hyun created SPARK-22557:
-------------------------------------
Summary: Use ThreadSignaler explicitly
Key: SPARK-22557
URL: https://issues.apache.org/jira/browse/SPARK-22557
Project: Spark
Issue Type: Bug
Components: Tests
Affects Versions: 2.3.0
Reporter: Dongjoon Hyun
Priority: Minor
ScalaTest 3.0 uses an implicit `Signaler`. This PR makes it sure all Spark
tests uses `ThreadSignaler` explicitly which has the same default behavior of
interrupting a thread on the JVM in ScalaTest 2.2.x. This will reduce potential
flakiness inside the other test suites.
