------------------------------
Summary: Set Spark master only if not set.
Key: BEAM-627
URL: https://issues.apache.org/jira/browse/BEAM-627
Project: Beam
Issue Type: Bug
Components: runner-spark
Reporter: Amit Sela
Assignee: Amit Sela
Currently, the Spark master is *always* set programatically.
This is an issue if the master was already set by passing a system property
(which is what spark-submit basically does).
Avoiding overrides allows for an application to define a "local" master, while
overriding it with an external resource manager.
