我正在使用scala中的clientapi与googlecloud大表一起工作，我试图创建一个具有单列族的表，但是我遇到了错误
下面是我写的代码：

`object TestBigtable {
  val columnFamilyName = Bytes.toBytes("cf1")
  def createConnection(ProjectId: String, InstanceID: String): Connection = {
    BigtableConfiguration.connect(ProjectId, InstanceID)
  }
  def createTableIfNotExists(connection: Connection, name: String) = {
    val tableName = TableName.valueOf(name)
    val admin = connection.getAdmin()
      if (!admin.tableExists(tableName)) {
        val tableDescriptor = new HTableDescriptor(tableName)
        tableDescriptor.addFamily(
          new HColumnDescriptor(columnFamilyName))
        admin.createTable(tableDescriptor)
      }
    }
  def runner(projectId: String,
             instanceId: String,
             tableName: String) = {
    val createTableConnection = createConnection(projectId, instanceId)
    try {
      createTableIfNotExists(createTableConnection, tableName)
    } finally {
      createTableConnection.close()
    }
  }`

一旦我执行jar，就会出现以下一组错误：

有人能帮我吗？
