Hi Ayan, Thank you for the response. I tried to connect to same "stand alone spark master" through spark-shell and it works as intended
On shell, tried ./spark-shell --master spark://host:7077 Connection was established and It wrote an info on console as 'Spark context available as 'sc' (master = spark://host:7077) But its issue when trying to connect to the same stand alone spark master through intellij scala code. 1. val <http://scala-lang.org/> conf = new <http://scala-lang.org/> SparkConf() 2. .setAppName("scala spark") 3. .setMaster("spark://host:7077") when setMaster is local, it just works, but when trying to connect spark stand alone (passing spark master url), it reports the above error.
