This PR adds an optional
app_name
argument toSparkConnection
which supports setting the Sparkspark.app.name
configuration setting. The default behavior is unchanged; by default the app name is "linking".This app name shows up in the Spark UI and possibly in resource managers like Mesos as well. Being able to set this for each run helps to distinguish between different runs.
