Andrew Or created SPARK-5816:
--------------------------------
Summary: Add huge backward compatibility warning in DriverWrapper
Key: SPARK-5816
URL: https://issues.apache.org/jira/browse/SPARK-5816
Project: Spark
Issue Type: Bug
Components: Deploy, Spark Core
Reporter: Andrew Or
Assignee: Andrew Or
Priority: Critical
As of Spark 1.3, we provide backward and forward compatibility in standalone
cluster mode through the REST submission gateway. HOWEVER, it nevertheless goes
through the legacy o.a.s.deploy.DriverWrapper, and the semantics of the command
line arguments there must not change. For instance, this was broken in commit
20a6013106b56a1a1cc3e8cda092330ffbe77cc3.
There is currently no warning against that in the class and so we should add
one before it's too late.
