<p>I am trying to run spark-on-k8s, While I reading stuff on internet I stumbled upon words 'Resource Staging Server'. </p>

<p>AFAIK that is server to sharing jars to executor. But when I issued commands with spark-submit. </p>

<pre><code>spark-2.3.1-bin-hadoop2.7/bin/spark-submit \
  --master k8s://k8s-url \
  --deploy-mode cluster \
  --name spark-pi \
  --class org.apache.spark.examples.SparkPi \
  --conf spark.executor.instances=2 \
  --conf spark.kubernetes.container.image=$I \
  local:///Users/myid/examples/target/spark-examples_2.11-2.4.0-SNAPSHOT-shaded.jar
</code></pre>

<p>That pod seems not to be created. </p>

<p>So where is source of Resource Staging Server(RSS)? 
Or is RSS still actively developed? </p>

ruseel
<p>RSS has been removed by Spark since version 2.3, but it still works at 2.2, spark on K8S.</p>

<p>BTW, RSS pod should be created manually before spark-submit.</p>
