Question

我正在使用Scala中的客户端API使用Google Cloud Big Table，我试图用一个单列族创建一个表，但出现错误

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()
    }


  }`

一旦执行我的jar，就会出现以下错误集：

有人可以帮助我吗？

将所罗门的评论重新发布为答案：

io.grpc.protobuf.lite在堆栈中。 Cloud Bigtable客户端原为从未使用protobuf lite测试。依赖图会有所帮助。作为一个快速修复，您也可以尝试使用bigtable-hbase-1.x阴影工件而不是bigtable-hbase-1.x工件。

您使用io.grpc.protobuf.lite可能导致问题。据我了解，io.grpc.protobuf.lite主要用于Android客户端。

使用带阴影的伪像应以较大的JAR大小和潜在的内存占用为代价，防止依赖性冲突。您可能还需要查看这些类似的问题报告以及解决方法：

使用HBASE客户端API创建一个大表
