I am trying to run above code using IntelliJ IDE. JavaRDD stringJavaRDD = sparkContext.textFile("nationalparks.csv") JavaSparkContext sparkContext = new JavaSparkContext(sparkConf) setMaster("local") // Delete this line when submitting to a cluster I have tried to create a sample application using spark and java. =hdfs://rhes75:9000/jars/spark-libs.I am new in spark framework.

Ģ) Create a directory on HDFS for the jars accessible to the applicationĤ) For a large cluster, increase the replication count of the Spark archive Jar cv0f spark-libs.jar -C $SPARK_HOME/jars/. Use the configuration option and set that to the location of an archive (you create on HDFS) containing all the JARs in the $SPARK_HOME/jars/ folder, at the root level of the archive. I have spent a fair bit of time on this and I recommend that you follow this procedure to make sure that the spark-submit job runs ok. In Yarn mode, it is important that Spark jar files are available throughout the Spark cluster. Spark-shell -driver-class-path /path/to/example.jar:/path/to/another.jar Options on spark-shell are similar to spark-submit hence you can use the options specified above to add one or multiple jars to spark-shell classpath.
Sometimes you may need to add a jar to only Spark driver, you can do this by using -driver-class-path or -conf This takes the high priority among other configs. On windows, the jar file names should be separated with comma (,) instead of colon (:) 2.4 Using SparkConf properties
