<div class="block">Configuration for a Spark application. Used to set various Spark parameters as key-value pairs.
<p>
Most of the time, you would create a SparkConf object with <code>new SparkConf()</code>, which will load
values from any <code>spark.*</code> Java system properties set in your application as well. In this case,
parameters you set directly on the <code>SparkConf</code> object take priority over system properties.
<p>
For unit tests, you can also call <code>new SparkConf(false)</code> to skip loading external settings and
get the same configuration no matter what the system properties are.
<p>
All setter methods in this class support chaining. For example, you can write
<code>new SparkConf().setMaster("local").setAppName("My app")</code>.
<p>
param: loadDefaults whether to also load values from Java system properties
