Hadoop – Apache Spark runs Spark-shell on Yarn error

I downloaded spark-2.1.0-bin-hadoop2.7.tgz from http://spark.apache.org/downloads.html. I have Hadoop HDFS and YARN with $ start-dfs.sh and $start-yarn.sh start. But running $spark-shell –master yarn –deploy-mode client gives the following error:

< pre>$spark-shell –master yarn –deploy-mode client
Setting default log level to “WARN”.
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel (newLevel).

Make sure your Hadoop configuration files The yarn-site.xml in the folder has the following properties:


yarn.nodemanager.pmem-check-enabled< br /> false



yarn.nodemanager.vmem-check-enabled
false
