1.统计需求
本章主要实现需求四:APP统计。需求如下:
2.代码编写
入口搭好:
AppStatProcessor.process(spark)
先看一下第一步的运行情况:
package com.imooc.bigdata.cp08.business
import com.imooc.bigdata.cp08.`trait`.DataProcess
import com.imooc.bigdata.cp08.utils.SQLUtils
import org.apache.spark.sql.SparkSession
object AppStatProcessor extends DataProcess{
override def process(spark: SparkSession): Unit = {
val sourceTableName = "ods"
val masterAddresses = "hadoop000"
val odsDF = spark.read.format("org.apache.kudu.spark.kudu")
.option("kudu.table",sourceTableName)
.option("kudu.master",masterAddresses)
.load()
odsDF.createOrReplaceTempView("ods")
val resultTmp = spark.sql(SQLUtils.APP_SQL_STEP1)
resultTmp.show()
}
}
其中SQL代码如下:
lazy val APP_SQL_STEP1 = "select appid,appname, " +
"sum(case when requestmode=1 and processnode >=1 then 1 else 0 end) origin_request," +
"sum(case when requestmode=1 and processnode >=2 then 1 else 0 end) valid_request," +
"sum(case when requestmode=1 and processnode =3 then 1 else 0 end) ad_request," +
"sum(case when adplatformproviderid>=100000 and iseffective=1 and isbilling=1 and isbid=1 and adorderid!=0 then 1 else 0 end) bid_cnt," +
"sum(case when adplatformproviderid>=100000 and iseffective=1 and isbilling=1 and iswin=1 then 1 else 0 end) bid_success_cnt," +
"sum(case when requestmode=2 and iseffective=1 then 1 else 0 end) ad_display_cnt," +
"sum(case when requestmode=3 and processnode=1 then 1 else 0 end) ad_click_cnt," +
"sum(case when requestmode=2 and iseffective=1 and isbilling=1 then 1 else 0 end) medium_display_cnt," +
"sum(case when requestmode=3 and iseffective=1 and isbilling=1 then 1 else 0 end) medium_click_cnt," +
"sum(case when adplatformproviderid>=100000 and iseffective=1 and isbilling=1 and iswin=1 and adorderid>20000 then 1*winprice/1000 else 0 end) ad_consumption," +
"sum(case when adplatformproviderid>=100000 and iseffective=1 and isbilling=1 and iswin=1 and adorderid>20000 then 1*adpayment/1000 else 0 end) ad_cost " +
"from ods group by appid,appname"
结果:
没毛病就往下跑第二个SQL,具体做法和需求三区别不大:
resultTmp.createOrReplaceTempView("app_tmp")
val result = spark.sql(SQLUtils.APP_SQL_STEP2)
result.show()
第二个SQL如下:
lazy val APP_SQL_STEP2 = "select appid,appname, " +
"origin_request," +
"valid_request," +
"ad_request," +
"bid_cnt," +
"bid_success_cnt," +
"bid_success_cnt/bid_cnt bid_success_rate," +
"ad_display_cnt," +
"ad_click_cnt," +
"ad_click_cnt/ad_display_cnt ad_click_rate," +
"ad_consumption," +
"ad_cost from app_tmp " +
"where bid_cnt!=0 and ad_display_cnt!=0"
然后run一下,都可以就可以写入Kudu了。
3.落地Kudu
val sinkTableName = "app_stat"
val partitionId = "appid"
val schema = SchemaUtils.APPSchema
KuduUtils.sink(result,sinkTableName,masterAddresses,schema,partitionId)
spark.read.format("org.apache.kudu.spark.kudu")
.option("kudu.master",masterAddresses)
.option("kudu.table",sinkTableName)
.load().show()
schema:
lazy val APPSchema: Schema = {
val columns = List(
new ColumnSchemaBuilder("appid", Type.STRING).nullable(false).key(true).build(),
new ColumnSchemaBuilder("appname", Type.STRING).nullable(false).key(true).build(),
new ColumnSchemaBuilder("origin_request", Type.INT64).nullable(false).build(),
new ColumnSchemaBuilder("valid_request", Type.INT64).nullable(false).build(),
new ColumnSchemaBuilder("ad_request", Type.INT64).nullable(false).build(),
new ColumnSchemaBuilder("bid_cnt", Type.INT64).nullable(false).build(),
new ColumnSchemaBuilder("bid_success_cnt", Type.INT64).nullable(false).build(),
new ColumnSchemaBuilder("bid_success_rate", Type.DOUBLE).nullable(false).build(),
new ColumnSchemaBuilder("ad_display_cnt", Type.INT64).nullable(false).build(),
new ColumnSchemaBuilder("ad_click_cnt", Type.INT64).nullable(false).build(),
new ColumnSchemaBuilder("ad_click_rate", Type.DOUBLE).nullable(false).build(),
new ColumnSchemaBuilder("ad_consumption", Type.DOUBLE).nullable(false).build(),
new ColumnSchemaBuilder("ad_cost", Type.DOUBLE).nullable(false).build()
).asJava
new Schema(columns)
}
看下结果:
OK收工!
