spark读写hbase性能对比

一、spark写入hbase

    hbase client以put方式封装数据，并支持逐条或批量插入。spark中内置saveAsHadoopDataset和saveAsNewAPIHadoopDataset两种方式写入hbase。为此，将同样的数据插入其中对比性能。

依赖如下：

1. put逐条插入
1.1 hbase客户端建表

create 'keyword1',{NAME=>'info',BLOCKSIZE=>'16384',BLOCKCACHE=>'false'},{NUMREGIONS=>10,SPLITALGO=>'HexStringSplit'}


1.2 code

       

val start_time1 = new Date().getTime
     
        keyword.foreachPartition(records =>{
     
          HBaseUtils1x.init()
     
          records.foreach(f => {
     
            val keyword = f.getString(0)
     
            val app_id = f.getString(1)
     
            val catalog_name = f.getString(2)
     
            val keyword_catalog_pv = f.getString(3)
     
            val keyword_catalog_pv_rate = f.getString(4)
     
            val rowKey = MD5Hash.getMD5AsHex(Bytes.toBytes(keyword+app_id)).substring(0,8)
     
            val cols = Array(keyword,app_id,catalog_name,keyword_catalog_pv,keyword_catalog_pv_rate)
     
            HBaseUtils1x.insertData(tableName1, HBaseUtils1x.getPutAction(rowKey, cf, columns, cols))
     
          })
     
          HBaseUtils1x.closeConnection()
     
        })
     
        var end_time1 =new Date().getTime
     
        println("HBase逐条插入运行时间为：" + (end_time1 - start_time1))



2.put批量插入
2.1 建表

create 'keyword2',{NAME=>'info',BLOCKSIZE=>'16384',BLOCKCACHE=>'false'},{NUMREGIONS=>10,SPLITALGO=>'HexStringSplit'}


2.2 代码

      

 val start_time2 = new Date().getTime
     
        keyword.foreachPartition(records =>{
     
          HBaseUtils1x.init()
     
          val puts = ArrayBuffer[Put]()
     
          records.foreach(f => {
     
            val keyword = f.getString(0)
     
            val app_id = f.getString(1)
     
            val catalog_name = f.getString(2)
     
            val keyword_catalog_pv = f.getString(3)
     
            val keyword_catalog_pv_rate = f.getString(4)
     
            val rowKey = MD5Hash.getMD5AsHex(Bytes.toBytes(keyword+app_id)).substring(0,8)
     
            val cols = Array(keyword,app_id,catalog_name,keyword_catalog_pv,keyword_catalog_pv_rate)
     
            try{
     
              puts.append(HBaseUtils1x.getPutAction(rowKey,
     
                cf, columns, cols))
     
            }catch{
     
              case e:Throwable => println(f)
     
            }
     
          })
     
          import collection.JavaConverters._
     
          HBaseUtils1x.addDataBatchEx(tableName2, puts.asJava)
     
          HBaseUtils1x.closeConnection()
     
        })
     
        val end_time2 = new Date().getTime
     
        println("HBase批量插入运行时间为：" + (end_time2 - start_time2))


3. saveAsHadoopDataset写入

    使用旧的Hadoop API将RDD输出到任何Hadoop支持的存储系统，为该存储系统使用Hadoop JobConf对象。JobConf设置一个OutputFormat和任何需要输出的路径，就像为Hadoop MapReduce作业配置那样。
3.1 建表

create 'keyword3',{NAME=>'info',BLOCKSIZE=>'16384',BLOCKCACHE=>'false'},{NUMREGIONS=>10,SPLITALGO=>'HexStringSplit'}


3.2 代码 

val start_time3 = new Date().getTime
     
        keyword.rdd.map(f =>{
     
          val keyword = f.getString(0)
     
          val app_id = f.getString(1)
     
          val catalog_name = f.getString(2)
     
          val keyword_catalog_pv = f.getString(3)
     
          val keyword_catalog_pv_rate = f.getString(4)
     
          val rowKey = MD5Hash.getMD5AsHex(Bytes.toBytes(keyword+app_id)).substring(0,8)
     
          val cols = Array(keyword,app_id,catalog_name,keyword_catalog_pv,keyword_catalog_pv_rate)
     
          (new ImmutableBytesWritable, HBaseUtils1x.getPutAction(rowKey, cf, columns, cols))
     
        }).saveAsHadoopDataset(HBaseUtils1x.getJobConf(tableName3))
     
        val end_time3 = new Date().getTime
     
        println("saveAsHadoopDataset方式写入运行时间为：" + (end_time3 - start_time3))


4. saveAsNewAPIHadoopDataset写入

    使用新的Hadoop API将RDD输出到任何Hadoop支持存储系统，为该存储系统使用Hadoop Configuration对象.Conf设置一个OutputFormat和任何需要的输出路径，就像为Hadoop MapReduce作业配置那样。
4.1 建表

create 'keyword4',{NAME=>'info',BLOCKSIZE=>'16384',BLOCKCACHE=>'false'},{NUMREGIONS=>10,SPLITALGO=>'HexStringSplit'}


4.2 code

   

val start_time4 = new Date().getTime
     
        keyword.rdd.map(f =>{
     
          val keyword = f.getString(0)
     
          val app_id = f.getString(1)
     
          val catalog_name = f.getString(2)
     
          val keyword_catalog_pv = f.getString(3)
     
          val keyword_catalog_pv_rate = f.getString(4)
     
          val rowKey = MD5Hash.getMD5AsHex(Bytes.toBytes(keyword+app_id)).substring(0,8)
     
          val cols = Array(keyword,app_id,catalog_name,keyword_catalog_pv,keyword_catalog_pv_rate)
     
          (new ImmutableBytesWritable, HBaseUtils1x.getPutAction(rowKey, cf, columns, cols))
     
        }).saveAsNewAPIHadoopDataset(HBaseUtils1x.getNewJobConf(tableName4,spark.sparkContext))
     
        val end_time4 = new Date().getTime
     
        println("saveAsNewAPIHadoopDataset方式写入运行时间为：" + (end_time4 - start_time4))



5. 性能对比
     

可以看出，saveAsHadoopDataset和saveAsNewAPIHadoopDataset方式要优于put逐条插入和批量插入。


二、spark读取hbase

newAPIHadoopRDD API可以将hbase表转化为RDD，具体使用如下：

val start_time1 = new Date().getTime
 
    val hbaseRdd = spark.sparkContext.newAPIHadoopRDD(HBaseUtils1x.getNewConf(tableName1), classOf[TableInputFormat], classOf[ImmutableBytesWritable], classOf[Result])
 
    println(hbaseRdd.count())
 
    hbaseRdd.foreach{
 
      case(_,result) => {
 
        // 获取行键
 
        val rowKey = Bytes.toString(result.getRow)
 
        val keyword = Bytes.toString(result.getValue(cf.getBytes(), "keyword".getBytes()))
 
        val keyword_catalog_pv_rate = Bytes.toDouble(result.getValue(cf.getBytes(), "keyword_catalog_pv_rate".getBytes()))
 
        println(rowKey + "," + keyword + "," + keyword_catalog_pv_rate)
 
      }
 
    }
