Question

尝试从Scala代码访问HBase时，我遇到了一个特殊的异常。

以下是该故事的长篇版本：

我在我的机器上以独立模式安装了HBase 1.2.6（Ubuntu 16.04）。接下来，我尝试执行以下代码：

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.")
    }
}

build.sbt文件：

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")

我使用以下命令从sbt执行代码：

$ sbt
> compile
> run

我收到以下错误：

行

时发生异常

val connection = ConnectionFactory.createConnection(config)

已到达。

对我来说没有意义。我希望有人能够对这一点有所了解。

删除此依赖项后，一切正常：

libraryDependencies += "org.apache.storm" % "storm-core" % "1.0.3"

显然一起使用Storm和HBase可能会有问题。（我不知道如何解决这个问题。）

连接到HBase时出现NoSuchMethodError异常
