Доброе утро,
У меня проблема с подключением Apache Spark с Hbase на AWS EMR кластер, я думаю, что проблема связана с несовместимостью "shc -core" и "json4s" , у меня всегда та же самая ошибка ниже, несмотря на то, что я изменяю версии "spark, scala, shc -core ".
Exception in thread "main" java.lang.NoSuchMethodError: org.json4s.jackson.JsonMethods$.parse(Lorg/json4s/JsonInput;Z)Lorg/json4s/JsonAST$JValue;

Конфигурация файла build.sbt ниже:
name := "hive_spark_hbase"
version := "1.0"
scalaVersion := "2.11.12"
val sparkVersion = "2.3.4"
resolvers += "jar_hortonworks" at "http://repo.hortonworks.com/content/groups/public"
libraryDependencies ++= Seq(
"org.scala-lang" % "scala-library" % scalaVersion.value,
"org.apache.spark" %% "spark-sql" % sparkVersion,
"org.apache.spark" %% "spark-sql-kafka-0-10" % sparkVersion,
"org.apache.spark" %% "spark-mllib" % sparkVersion,
"com.hortonworks" % "shc-core" % "1.1.1-2.1-s_2.11"
)
Мой основной класс для загрузки данных в Hbase:
import org.apache.spark.sql.DataFrame
import org.apache.spark.sql.execution.datasources.hbase._
import org.apache.spark.sql.execution.datasources.hbase.HBaseTableCatalog
import org.apache.spark.sql.SparkSession
import org.apache.spark.SparkConf
import org.apache.spark.sql.SQLContext
import org.apache.spark.SparkConf
case class Employee(id:String , name: String , lastname: String , mname:String , adress:String , city:String , state : String , zipcode : String)
object Dataflow {
def main(args: Array[String]): Unit = {
val catalog=
s"""{
|"table":{"namespace":"default","name":"employee"},
|"rowkey":"key",
|"columns":{
|"key":{"cf":"rowkey","col":"key","type":"string"},
|"fName":{"cf":"person","col":"firstName","type":"string"},
|"lName":{"cf":"person","col":"lastName","type":"string"},
|"mName":{"cf":"person","col":"middleName","type":"string"},
|"addressLine":{"cf":"address","col":"addressLine","type":"string"},
|"city":{"cf":"address","col":"city","type":"string"},
|"state":{"cf":"address","col":"state","type":"string"},
|"zipCode":{"cf":"address","col":"zipCode","type":"string"}
|}
|}""".stripMargin
val data=Seq(
Employee("1","Abby","Smith","K","3456main","Orlando","FL","45235"),
Employee("2","Amaya","Williams","L","123Orange","Newark","NJ","27656"),
Employee("3","Alchemy","Davis","P","Warners","Sanjose","CA","34789")
)
val master = "yarn"
val appName = "MyApp"
val conf: SparkConf = new SparkConf()
.setMaster(master)
.setAppName(appName)
.set("spark.driver.allowMultipleContexts", "false")
.set("spark.ui.enabled", "false")
val spark = SparkSession.builder().config(conf).getOrCreate()
import spark.implicits._
val df=spark.sparkContext.parallelize(data).toDF
df.write.options(
Map(HBaseTableCatalog.tableCatalog->catalog,HBaseTableCatalog.newTable->"4"))
.format("org.apache.spark.sql.execution.datasources.hbase")
.save()
}
}
И, наконец, отправка Spark Job вроде этого:
spark-submit --class Dataflow --master yarn --packages com.hortonworks:shc-core:1.1.1-2.1-s_2.11 --repositories http://repo.hortonworks.com/content/groups/public/ --files /etc/hbase/conf/hbase-site.xml /home/hadoop/spark_hbase/target/scala-2.11/hive_spark_hbase_2.11-1.0.jar
Спасибо большое .
