----------------------------
Summary: Wrong warning of "WARN Master: App app-xxx requires more
resource than any of Workers could have."
Key: SPARK-31921
URL: https://issues.apache.org/jira/browse/SPARK-31921
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 3.0.0
Reporter: wuyi
When start spark-shell using local cluster mode, e.g. ./bin/spark-shell
--master "local-cluster[2, 1, 1024]", there will be a warning:
{code:java}
20/06/06 22:09:09 WARN Master: App app-20200606220908-0000 requires more
resource than any of Workers could have.
{code}
which means the application can not get enough resources to launch at least one
executor.
But that's not true since we can successfully complete a job.
