Hive-On-Tez测试

在MRR和MPJ计算模型的处理上，TEZ能够提升的性能较为明显，具体测试如下：

MRR计算模型测试

• 测试表格

  1.users(id,name,password): 数据总量1千万条记录；

  2.peoples(id,name,gender,address): 数据总量1千万条记录；

  3.gender_summary(gender,count)

  3.address_summary(address,count)

• 测试语句

  FROM (SELECT u.username, p.sex, p.address FROM users u 
      JOIN peoples p ON u.userid = p.id) 
  subql
  INSERT OVERWRITE TABLE gender_summary 
      SELECT subql.sex, count(*) GROUP BY subql.sex
  INSERT OVERWRITE TABLE address_summary 
      SELECT subql.address, count(*) GROUP BY subql.address;
  					

• DAG有向无环图如下：

  
  

• 执行结果

  1. 基于MapReduce运行

     MapReduce Jobs Launched: 
     Stage-Stage-2: Map: 2  Reduce: 3   Cumulative CPU: 220.78 sec
     Stage-Stage-3: Map: 1  Reduce: 1   Cumulative CPU: 4.23 sec
     Stage-Stage-4: Map: 1  Reduce: 1   Cumulative CPU: 4.08 sec
     Total MapReduce CPU Time Spent: 3 minutes 49 seconds 90 msec
     Time taken: 186.853 seconds
     3次执行分别用时：186.853、188.748、191.812，平均用时：189.13秒。
     							

  2. 基于TEZ运行

             VERTICES      STATUS  TOTAL  COMPLETED  RUNNING  PENDING  FAILED  KILLED
     --------------------------------------------------------------------------------
     Map 1 ..........   SUCCEEDED      5          5        0        0       0       0
     Map 5 ..........   SUCCEEDED      6          6        0        0       0       0
     Reducer 2 ......   SUCCEEDED      2          2        0        0       0       0

     Reducer 4 ......   SUCCEEDED      1          1        0        0       0       0
     --------------------------------------------------------------------------------
     VERTICES: 05/05  [==========================>>] 100%  ELAPSED TIME: 56.23 s    
     --------------------------------------------------------------------------------
     Time taken: 60.348 seconds
     3次执行分别用时：60.348、60.441、61.311，平均用时：60.7秒。
     							

  时间效率上提升了近3倍左右。

MPJ计算模型测试

• 测试表格

  1.users(id,name,password): 数据总量1千万条记录；

  2.peoples(id,name,gender,address): 数据总量1千万条记录；

  3.permissions(userid,name)

• 测试语句

  SELECT u.userid, p.name, q.name FROM users u 
      JOIN peoples p ON u.userid = p.id 
      JOIN permissions q ON p.id = q.userId;
  					

• DAG有向无环图如下：
