title: apache-spark startup error on alpine linux docker
body: <p>*I followed <a href="https://www.anchormen.nl/spark-docker/" rel="nofollow noreferrer">https://www.anchormen.nl/spark-docker/</a> and 
  When i executed the command ,apache startup fails saying "--" is not recognized.
  I am very new to spark.Requesting help from our trusted community members.</p>
  
  <pre><code>bash /opt/spark/sbin/start-master.sh
  starting org.apache.spark.deploy.master.Master, logging to /opt/spark/logs/spark--org.apache.spark.deploy.master.Master-1-e6b8f9219a40.out
  failed to launch: nice -n 0 /opt/spark/bin/spark-class org.apache.spark.deploy.master.Master --host e6b8f9219a40 --port 7077 --webui-port 8080

  <p>*
  Only difference from the article is that i used alpine linux,which am restricted to.</p>
  
  <p>to verify i tried to cat the log file..and got the same error. alpine linux in docker is not recognizing "--" .am i doing something wrong?</p>
  
  <p>[SOLVED] thanks Robert.</p>
