Spark2.1.0 incompatible Jackson versions 2.7.6

Question

I am trying to run a simple spark example in intellij, but I get the error like that:

Exception in thread "main" java.lang.ExceptionInInitializerError
at org.apache.spark.SparkContext.withScope(SparkContext.scala:701)
at org.apache.spark.SparkContext.textFile(SparkContext.scala:819)

at org.apache.spark.rdd.RDDOperationScope$.<clinit>(RDDOperationScope.scala)

I have try to update my Jackson dependency, but it seems not work, I do this:

libraryDependencies += "com.fasterxml.jackson.core" % "jackson-core" % "2.8.7"
libraryDependencies += "com.fasterxml.jackson.core" % "jackson-databind" % "2.8.7"

but it still appear the same error messages, can some one help me to fix the error?

Here is spark example code:

object test {
def main(args: Array[String]): Unit = {
    if (args.length < 1) {
        System.err.println("Usage: <file>")
        System.exit(1)
    }

    val conf = new SparkConf()
    val sc = new SparkContext("local","wordcount",conf)
    val line = sc.textFile(args(0))

    line.flatMap(_.split(" ")).map((_, 1)).reduceByKey(_+_).collect().foreach(println)

    sc.stop()
    }
}

And here is my built.sbt:

name := "testSpark2"

version := "1.0"

scalaVersion := "2.11.8"


libraryDependencies += "com.fasterxml.jackson.core" % "jackson-core" % "2.8.7"
libraryDependencies += "com.fasterxml.jackson.core" % "jackson-databind" % "2.8.7"

libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-mllib_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-repl_2.11" % "2.1.0"

libraryDependencies += "org.apache.spark" % "spark-mesos_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-graphx_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-catalyst_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-launcher_2.11" % "2.1.0"

Spark 2.1.0 contains com.fasterxml.jackson.core as transitive dependency. So, we do not need to include then in libraryDependencies.

But if you want to add a different com.fasterxml.jackson.core dependencies' version then you have to override them. Like this:

name := "testSpark2"

version := "1.0"

scalaVersion := "2.11.8"


dependencyOverrides += "com.fasterxml.jackson.core" % "jackson-core" % "2.8.7"
dependencyOverrides += "com.fasterxml.jackson.core" % "jackson-databind" % "2.8.7"
dependencyOverrides += "com.fasterxml.jackson.module" % "jackson-module-scala_2.11" % "2.8.7"

libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-mllib_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-repl_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-streaming-flume_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-sql_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-network-shuffle_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-streaming-kafka-0-10_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-hive_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-streaming-flume-assembly_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-mesos_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-graphx_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-catalyst_2.11" % "2.1.0"
libraryDependencies += "org.apache.spark" % "spark-launcher_2.11" % "2.1.0"

So, change your build.sbt like the one above and it will work as expected.

I hope it helps!

@hey_you: can you provide your `build.sbt` file? – himanshuIIITian Jan 17 '19 at 09:55 — himanshuIIITian, Jan 17 '19 at 09:55

FYI. For my case, I'm using spark and kafka-streams in the app, while kafka-streams uses com.fasterxml.jackson.core 2.8.5. Adding exclude as below fixed the issue

(gradle)

compile (group: "org.apache.kafka", name: "kafka-streams", version: "0.11.0.0"){
    exclude group:"com.fasterxml.jackson.core"
}

Were you having the exact same problem? Incompatible Jackson version? – Filipe Miranda Sep 25 '18 at 19:07

Solution with Gradle, by using the resolutionStrategy (https://docs.gradle.org/current/dsl/org.gradle.api.artifacts.ResolutionStrategy.html):

configurations {

    all {

        resolutionStrategy {
            force 'com.fasterxml.jackson.core:jackson-core:2.4.4', 'com.fasterxml.jackson.core:jackson-databind:2.4.4', 'com.fasterxml.jackson.core:jackson-annotations:2.4.4'
        }
    }
}
