Connect From Rstudio to Hadoop mapr cluster using sparklyr package

We are trying to establish the connection from rstudio to hadoop mapr cluster to read the data from hive data base. While connecting we faced below issue.

config <- list(spark.env.SPARK_LOCAL_IP = "10.21.1.162",

•            spark.env.SPARK_PUBLIC_DNS = "10.21.1.162", 
  

•            spark.env.SPARK_LOCAL_HOSTNAME= "10.21.1.162")
  

sc <- spark_connect("yarn-client", config = config, version = "2.0.1") Error in force(code) : Failed while connecting to sparklyr to port (8880) for sessionid (68257): Gateway in port (8880) did not respond.
