I want to process hive table using spark, but when I run my program, I got this error:
Exception in thread "main" java.lang.IllegalArgumentException: Unable to instantiate SparkSession with Hive support because Hive classes are not found.
My application code

You should remove provided for your spark-hive dependency:
"org.apache.spark" %% "spark-hive" % "2.3.2" % "provided"
change to
"org.apache.spark" %% "spark-hive" % "2.3.2"

Requirement: Read data from DynamoDB(not local but on AWS) via Spark using Scala from my local machine.
Understanding: Data can be read using the emr-hadoop-dynamodb.jar when we are using an EMR cluster
Question:
Can we read data from DynamoDB(on cloud and not local) using the emr-dynamodb-hadoop.jar?
EMR cluster is not to be used. I directly want to access dynamodb from spark using scala code on my local machine

This was solved when the following dependency version were updated

I am trying to integrate spark streaming with kafka. I am unable to resolve dependency for org.apache.spark.streaming.kafka.KafkaUtils. Below is my build.sbt:
name := "StreamingTest"
version := "1.0"
organization := "com.sundogsoftware"
scalaVersion := "2.12.10"
libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % "3.0.0-preview2" % "provided",
"org.apache.spark" %% "spark-streaming-kafka-0-10" % "3.0.0-preview2",
"org.apache.spark" %% "spark-sql" % "3.0.0-preview2",
"org.apache.spark" %% "spark-streaming" % "3.0.0-preview2" % "provided",
"org.apache.kafka" %% "kafka" % "2.0.0"
)
I am using following imports in my project:
import org.apache.spark.{SparkConf, SparkContext, sql}
import org.apache.spark.sql.{SQLContext, SparkSession}
import org.apache.spark.streaming.{Seconds, StreamingContext}
import org.apache.spark.streaming.dstream.{DStream, InputDStream}
import org.apache.spark.streaming.kafka.KafkaUtils
import kafka.serializer.StringDecoder
All the dependecies are resolved except org.apache.spark.streaming.kafka.KafkaUtils. I am using spark version 3.0.0-preview2 and scala version 2.12.10.
I was trying to use the following dependencies in my build.sbt, but it keeps giving "unresolved dependency" issue.
libraryDependencies += "org.apache.bahir" %% "spark-streaming-twitter_2.11" % "2.2.0.1.0.0-SNAPSHOT"
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "2.2.0"
I'm using Spark 2.2.0. What are the correct dependencies?
The question was posted a while ago, but I ran into the same problem this week. Here is the solution for those who still have the problem :
As you can see here, the correct syntax of the artifact for importing the lib with SBT is "spark-streaming-twitter", while with Maven it is "spark-streaming-twitter_2.11". It is because, for some reason, when importing with SBT, the Scala version is appended later (the last number is truncated).
But the thing is that the only artifact that work is "spark-streaming-twitter_2.11". For example, with a Scala 2.12, you will have the error
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: UNRESOLVED DEPENDENCIES ::
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: org.apache.bahir#spark-streaming-twitter_2.12;2.3.2: not found
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
But if you use Scala 2.11, it should work fine. Here is a working sbt file :
name := "twitter-read"
version := "0.1"
scalaVersion := "2.11.12"
libraryDependencies += "org.apache.spark" %% "spark-core" % "2.4.2"
libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.4.2"
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "2.4.2" % "provided"
libraryDependencies += "org.twitter4j" % "twitter4j-core" % "3.0.3"
libraryDependencies += "org.twitter4j" % "twitter4j-stream" % "3.0.3"
libraryDependencies += "org.apache.bahir" %% "spark-streaming-twitter" % "2.3.2"
Below are the dependencies you need to add for Spark-Twitter Streaming.
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-streaming_2.11</artifactId>
<version>2.0.0</version>
</dependency>

I'm trying to execute locally a job in the spark-jobserver. My application has the dependencies below:
name := "spark-test"
version := "1.0"
scalaVersion := "2.10.6"
resolvers += Resolver.jcenterRepo
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.6.1"
libraryDependencies += "spark.jobserver" %% "job-server-api" % "0.6.2" % "provided"
libraryDependencies += "com.datastax.spark" %% "spark-cassandra-connector" % "1.6.2"
libraryDependencies += "org.apache.spark" %% "spark-sql" % "1.6.2"
libraryDependencies += "com.holdenkarau" % "spark-testing-base_2.10" % "1.6.2_0.4.7" % "test"
I've generated the application package using:
sbt assembly
After that, I've submitted the package like this:
curl --data-binary #spark-test-assembly-1.0.jar localhost:8090/jars/myApp
When I triggered the job, I got the following error:
{

},
"status": "ERROR",
"jobId": "a6bd6f23-cc82-44f3-8179-3b68168a2aa7"
}
Here is the part of the application that is failing:
override def runJob(sparkCtx: SparkContext, config: Config): Any = {
val sqlContext = new SQLContext(sparkCtx)
...
}
I have some questions:
1) I've noticed that to run spark-jobserver local I don't need to have spark installed. Does spark-jobserver already come with spark embedded?
2) How do I know what is the version of the spark that is being used by spark-jobserver? Where is that?
3) I'm using the version 1.6.2 of the spark-sql. Should I change it or keep it?
If anyone can answer my questions, I will be very grateful.
Yes, spark-jobserver has spark dependencies. Instead of job-server/reStart you should use job-server-extras/reStart which will help you to get sql related dependencies.
Look at project/Versions.scala
You don't need spark-sql I think because it is included if you run job-server-extras/reStart
My requirement is creating the rest json from the request uri using spray. I am using requestUri directive to get the base URL. When I run it through IDE or through spark-submit locally on my system, I got the proper output. But when I have done spark-submit on the cluster, I am not getting the base url using requestUri directive.The url, I am getting is partial. Because of which the expected output is also not proper.
The code to get the url is
requestUri {
uri =>
val reqUri = s"$uri"//uri.toString()
complete {
println ("URI " + reqUri)
}
}
build.sbt looks like this
scalaVersion := "2.10.5"
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.4.0"
resolvers ++= Seq(
"Akka Repository" at "http://repo.akka.io/releases/")
resolvers ++= Seq("Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/",
"Spray Repository" at "http://repo.spray.io")
libraryDependencies +=
"com.typesafe.akka" %% "akka-actor" % "2.3.0"
libraryDependencies ++= {
val sprayVersion = "1.3.1"
Seq(
"io.spray" %% "spray-can" % sprayVersion,
"io.spray" %% "spray-routing" % sprayVersion,
"io.spray" %% "spray-json" % sprayVersion
)
}
Please let me know how I can I fix this issue.All your suggestions are valuable. Thanks in advance.
