Je reçois une exception particulière lorsque j'essaie d'accéder à HBase à partir du code Scala.Exception NoSuchMethodError lors de la connexion à HBase
Voici la version longue de cette histoire:
J'ai installé HBase 1.2.6 en mode autonome sur ma machine (Ubuntu 16.04). Ensuite j'ai essayé d'exécuter le code suivant:
import org.apache.hadoop.conf.Configuration
import org.apache.hadoop.hbase.client.ConnectionFactory
import org.apache.hadoop.hbase.io.compress.Compression.Algorithm
import org.apache.hadoop.hbase.{HBaseConfiguration, HColumnDescriptor, HTableDescriptor, TableName}
object HelloWorld {
private val TABLE_NAME = "MY_TABLE_NAME_TOO"
private val CF_DEFAULT = "DEFAULT_COLUMN_FAMILY"
def main(args: Array[String]): Unit = {
val config: Configuration = HBaseConfiguration.create()
val connection = ConnectionFactory.createConnection(config)
val admin = connection.getAdmin
val table = new HTableDescriptor(TableName.valueOf(TABLE_NAME))
table.addFamily(new HColumnDescriptor(CF_DEFAULT).setCompressionType(Algorithm.NONE))
System.out.print("Creating table. ")
admin.createTable(table)
System.out.println(" Done.")
}
}
Le fichier build.sbt:
name := "myapp"
version := "1.0"
scalaVersion := "2.12.1"
libraryDependencies += "org.apache.storm" % "storm-core" % "1.0.3"
libraryDependencies += "org.apache.hbase" % "hbase-client" % "1.2.6" exclude("org.slf4j","slf4j-log4j12")
libraryDependencies += "org.apache.hbase" % "hbase-common" % "1.2.6" exclude("org.slf4j","slf4j-log4j12")
libraryDependencies += "org.apache.hadoop" % "hadoop-common" % "2.8.0" exclude("org.slf4j","slf4j-log4j12")
libraryDependencies += "org.apache.hbase" % "hbase-protocol" % "1.2.6" exclude("org.slf4j","slf4j-log4j12")
J'exécute le code de SBT en utilisant ces commandes:
$ sbt
> compile
> run
Je reçois l'erreur suivante :

l'exception se produit lorsque la ligne
val connection = ConnectionFactory.createConnection(config)
est atteinte.
Cela n'a aucun sens pour moi. J'espère que quelqu'un peut faire la lumière sur celui-ci.
