----------------------------------------
Summary: SparkConf.setIfMissing should only evaluate the assigned
value if indeed missing
Key: SPARK-6630
URL: https://issues.apache.org/jira/browse/SPARK-6630
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 1.3.0
Reporter: Svend Vanderveken
Priority: Minor
The method setIfMissing() in SparkConf is currently systematically evaluating
the right hand side of the assignment event if not used. This leads to
unnecessary computation, like in the case of
```
conf.setIfMissing("spark.driver.host", Utils.localHostName())
```
