--------------------------------
Summary: Warn against deprecated YARN settings
Key: SPARK-4730
URL: https://issues.apache.org/jira/browse/SPARK-4730
Project: Spark
Issue Type: Bug
Components: YARN
Affects Versions: 1.2.0
Reporter: Andrew Or
Assignee: Andrew Or
Yarn currently reads from SPARK_MASTER_MEMORY and SPARK_WORKER_MEMORY. If you
have these settings leftover from a standalone cluster setup and you try to run
Spark on Yarn on the same cluster, then your executors suddenly get the amount
of memory specified through SPARK_WORKER_MEMORY.
This behavior is due in large part to backward compatibility. However, we
should log a warning against the use of these variables at the very least.
