Scala:创建基于行键的带预分割区域的HBase表

import org.apache.hadoop.hbase.{HBaseConfiguration, HColumnDescriptor, HTableDescriptor, TableName}
import org.apache.hadoop.hbase.client.{Admin, Connection, ConnectionFactory}

object HBaseTableCreator {
  def createTable(tableName: String, columnFamily: String, splitKeys: Array[String]): Unit = {
    val conf = HBaseConfiguration.create()
    val connection: Connection = ConnectionFactory.createConnection(conf)
    val admin: Admin = connection.getAdmin

    val tableDescriptor = new HTableDescriptor(TableName.valueOf(tableName))
    val columnDescriptor = new HColumnDescriptor(columnFamily)
    tableDescriptor.addFamily(columnDescriptor)

    admin.createTable(tableDescriptor, splitKeys.map(Bytes.toBytes))
    admin.close()
    connection.close()
  }

  def main(args: Array[String]): Unit = {
    val tableName = "my_table"
    val columnFamily = "cf"
    val splitKeys = Array("key1", "key2", "key3") // 预分割区域的行键

    createTable(tableName, columnFamily, splitKeys)
  }
