<pre class="base-tree">
object --+
|
<strong class="uidshort">SparkConf</strong>
</pre>
<hr />
<p>Configuration for a Spark application. Used to set various Spark
parameters as key-value pairs.</p>
<p>Most of the time, you would create a SparkConf object with
<code>SparkConf()</code>, which will load values from
<code>spark.*</code> Java system properties as well. In this case, any
parameters you set directly on the <code>SparkConf</code> object take
priority over system properties.</p>
<p>For unit tests, you can also call <code>SparkConf(false)</code> to
skip loading external settings and get the same configuration no matter
what the system properties are.</p>
<p>All setter methods in this class support chaining. For example, you
can write <code>conf.setMaster("local").setAppName("My
app")</code>.</p>
<p>Note that once a SparkConf object is passed to Spark, it is cloned and
can no longer be modified by the user.</p>
