It looks like, you are trying to open a file which doesn't exist. The fisrt line of the error message says so:

I am doing a tutorial on Pluralsight for Apache Spark which is a simple word counter. I am on Windows 11 and I have IntelliJ IDEA 2022.3.1 (Ultimate Edition). Additionally, on my machine I have JKD8, Apache Spark 3.3.1 pre built for Hadoop 3.3 and later, and Hadoop 3.3.4. The code is written in Scala with SBT as the build tooland I've included the code below. After packaging the file with sbt package I run the command
spark-submit --class "main.WordCount" --master "local[*]" "C:\Users\user\Documents\Projects\WordCount\target\scala-2.11\word-count_2.11-0.1.jar"
I am receiving an exception
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO$POSIX.stat(Ljava/lang/String;)Lorg/apache/hadoop/io/nativeio/NativeIO$POSIX$Stat; (Full log below)
I have my dev tools (Java, Spark, Hadoop, etc) under C:\DevTools\TOOL and the Windows Environment variables are set as follows:
JAVA_HOME -> C:\DevTools\TOOL\Java
SPARK_HOME -> C:\DevTools\TOOL\Spark
HADOOP_HOME -> C:\DevTools\TOOL\Hadoop
PATH -> %JAVA_HOME%\bin; %SPARK_HOME%\bin; %HADOOP_HOME%\bin
Lastly, I've downloaded various winutils.exe and and hadoop.dll and I've put them in the Spark bin folder and the Hadoop bin folder but nothing seemingly works. Does anyone have any suggestions as to how I can get this to execute successfully?
build.sbt
name := "Word Count"
version := "0.1"
scalaVersion := "2.11.8"
val sparkVersion = "1.6.1"
libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % sparkVersion,
"org.apache.spark" %% "spark-streaming" % sparkVersion
)
WordCount.scala
package main
import org.apache.spark.SparkContext
import org.apache.spark.SparkConf
object WordCount {
def main (args: Array[String]): Unit = {
val configuration = new SparkConf().setAppName("Word Counter")
val sparkContext = new SparkContext(configuration)
val textFile = sparkContext.textFile("file:///DevTools/TOOL/Spark")
val tokenizedFileData = textFile.flatMap(line=>line.split(" "))
val countPrep = tokenizedFileData.map(word=>(word, 1))
val counts = countPrep.reduceByKey((accumValue, newValue)=>accumValue + newValue)
val storedCounts = counts.sortBy(kvPair=>kvPair._2, false)
storedCounts.saveAsTextFile("file:///DevTools/TOOL/Spark/output")
}
}

)
Are you running this into a Databricks instance?
If not, that's the problem: dbutils are provided by Databricks execution context.
In that case, as far as I know, you have three options:
Package your application into a jar file and run it using a Databricks job
Use databricks-connect
Try to emulate a mocked dbutils instance outside Databricks as shown here:
com.databricks.dbutils_v1.DBUtilsHolder.dbutils0.set(
new com.databricks.dbutils_v1.DBUtilsV1{
...
}
)
Anyway, I'd say that options 1 and 2 are better than the third one. Also by choosing one of those you don't need to include "dbutils-api_2.11" dependency, as it is provided by Databricks cluster.
I am beginning using Spark streaming. I want to get a stream from Kafka with a sample code I found on the Spark documentation : https://spark.apache.org/docs/2.1.0/streaming-kafka-0-10-integration.html
Here is my code :
object SparkStreaming {
def main(args: Array[String]) {
val conf = new SparkConf().setAppName("Test_kafka_spark").setMaster("local[*]") // local parallelism 1
val ssc = new StreamingContext(conf, Seconds(1))
val kafkaParams = Map[String, Object](
"bootstrap.servers" -> "localhost:9093",
"key.deserializer" -> classOf[StringDeserializer],
"value.deserializer" -> classOf[StringDeserializer],
"group.id" -> "test",
"auto.offset.reset" -> "latest",
"enable.auto.commit" -> (false: java.lang.Boolean)
)
val topics = Array("spark")
val stream = KafkaUtils.createDirectStream[String, String](
ssc,
PreferConsistent,
Subscribe[String, String](topics, kafkaParams)
)
stream.map(record => (record.key, record.value))
}
}
All seemed to start well at but the job stopped immediately, logs as follow :

Thanks for any help.
It appears you haven't started your StreamingContext.
Try adding these 2 lines at the end
ssc.start
ssc.awaitTermination
You did not call any action on DStream, so nothing gets executed (map is a transformation and is lazy), also you need to start the StreamingContext.
Please look into this complete example.
https://github.com/apache/spark/blob/master/examples/src/main/scala/org/apache/spark/examples/streaming/DirectKafkaWordCount.scala
I have a maven scala application that submits a spark job to Spark standalone single node cluster. When job is submitted, Spark application tries to access cassandra, which is hosted on Amazon EC2 instance, using spark-cassandra-connector. Connection is established, but results are not returned. After some time connector disconnects. It works fine if I'm running spark in local mode.
I tried to create simple application and my code looks like this:
val sc = SparkContextLoader.getSC
def runSparkJob():Unit={
val table =sc.cassandraTable("prosolo_logs_zj", "logevents")
println(table.collect().mkString("\n"))
}
SparkContext.scala
object SparkContextLoader {
val sparkConf = new SparkConf()
sparkConf.setMaster("spark://127.0.1.1:7077")
sparkConf.set("spark.cores_max","2")
sparkConf.set("spark.executor.memory","2g")
sparkConf.set("spark.serializer", "org.apache.spark.serializer.KryoSerializer")
sparkConf.setAppName("Test application")
sparkConf.set("spark.cassandra.connection.host", "xxx.xxx.xxx.xxx")
sparkConf.set("spark.cassandra.connection.port", "9042")
sparkConf.set("spark.ui.port","4041")
val oneJar="/samplesparkmaven/target/samplesparkmaven-jar.jar"
sparkConf.setJars(List(oneJar))
#transient val sc = new SparkContext(sparkConf)
}
Console output looks like:

I'm using
scala 2.11.6
spark 2.1.0 (both for standalone spark and dependency in application)
spark-cassandra-connector 2.0.0-M3
Cassandra Java driver 3.0.0
Apache Cassandra 3.9
Version compatibility table for cassandra connector doesn't show any problem with it, but I can't figure out anything else that might be the problem.
I've finally solved the problem I had. It turned out to be the problem with path. I was using local path to the jar, but missed to add "." at the beginning, so it was treated as absolute path.
Unfortunately, there was no exception in the application indicating that file doesn't exist on the provided path, and the only exception I had was from the worker which could not find jar file in the Spark cluster.
