----------------------------
Summary: Master fall into dead loop while launching executor
failed in Worker
Key: SPARK-27510
URL: https://issues.apache.org/jira/browse/SPARK-27510
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.4.0, 2.3.0, 2.2.0, 2.1.0, 2.0.0, 1.6.0
Reporter: wuyi
In Standalone, while launching executor during ExecutorRunner.start() is always
failed in Worker, Master will continue to launch new executor for the same
Worker indefinitely.
The issue is easy to reproduce by running a unit test with local-cluster mode
and set a wrong spark.test.home(e.g. /tmp). Then, when running unit test, test
would get stuck and we can see endless executor directories under
/tmp/work/app/.
