一、编程实现工具类：

### --- 编程实现工具类一：ConnHBase

package myutils

import org.apache.hadoop.conf.Configuration
import org.apache.hadoop.hbase.{HBaseConfiguration, HConstants}
import org.apache.hadoop.hbase.client.{Connection, ConnectionFactory}

class ConnHBase {
  def connToHbase:Connection ={
    val conf : Configuration = HBaseConfiguration.create()
    conf.set("hbase.zookeeper.quorum","hadoop01,hadoop02,hadoop03")
    //    conf.set("hbase.zookeeper.quorum","hadoop01,hadoop02,hadoop03")
    conf.set("hbase.zookeeper.property.clientPort","2181")
    conf.setInt(HConstants.HBASE_CLIENT_OPERATION_TIMEOUT,30000)
    conf.setInt(HConstants.HBASE_CLIENT_SCANNER_TIMEOUT_PERIOD,30000)
    val connection = ConnectionFactory.createConnection(conf)
    connection
  }

}

### --- 编程实现工具类二：SourceKafka

package myutils

import java.util.Properties
import org.apache.flink.api.common.serialization.SimpleStringSchema
import org.apache.flink.streaming.connectors.kafka.FlinkKafkaConsumer

class SourceKafka {
  def getKafkaSource(topicName: String) : FlinkKafkaConsumer[String] = {
    val props = new Properties()
    props.setProperty("bootstrap.servers","hadoop01:9092,hadoop02:9092,hadoop03:9092");//3,4
    props.setProperty("group.id","consumer-group")
    props.setProperty("key.deserializer","org.apache.kafka.common.serialization.StringDeserializer")
    props.setProperty("value.deserializer","org.apache.kafka.common.serialization.StringDeserializer")
    props.setProperty("auto.offset.reset","la")

    new FlinkKafkaConsumer[String](topicName, new SimpleStringSchema(),props);
  }
}
