其实就是获取上图的start key和end key

• 代码:

object HbaseRegions {
  def main(args: Array[String]): Unit = {
    val hconf: Configuration = HBaseConfiguration.create()
    hconf.set("hbase.zookeeper.property.clientPort", "2181")
    hconf.set("hbase.zookeeper.quorum", "node118,node119,node120")
    hconf.set("hbase.master", "node118:16000")
    val hbaseConn: Connection = ConnectionFactory.createConnection(hconf)
    val tableName: TableName = TableName.valueOf("OFFICIAL", "SAMPLE_INFO")
    val table: Table = hbaseConn.getTable(tableName)

    val startKeys: Array[Array[Byte]] = table.getRegionLocator.getStartKeys
    val endKeys: Array[Array[Byte]] = table.getRegionLocator.getEndKeys

    startKeys.zip(endKeys).foreach(kv=>{
      println((Bytes.toString(kv._1), Bytes.toString(kv._2)))
    })
    table.close()
    hbaseConn.close()
  }
}
