7.10 生成数据

1. 先查看eventlog表中的数据情况

   xxxxxxxxxx
   hbase(main):004:0> count 'eventlog'
   3 row(s)
   Took 0.1625 seconds                                         => 3
   

2. 将eventlog表中的数据清空

   xxxxxxxxxx
   hbase(main):005:0> truncate 'eventlog'
   Truncating 'eventlog' table (it may take a while):
   Disabling table...
   Truncating table...
   Took 3.5537 seconds                                                                          
   hbase(main):006:0> count 'eventlog'
   0 row(s)
   Took 2.3821 seconds                                         => 0
   

3. 打开test\java包下 cn.itbaizhan.test.TestDataMaker，修改59行的日期

   xxxxxxxxxx
   Date d = tDataMaker.getDate("20220120");
   

   运行当前类。

4. 查看数据是否添加成功

   xxxxxxxxxx
   hbase(main):007:0> count 'eventlog'
   Current count: 1000, row: 1642694315000_66495598                                             
   1000 row(s)
   Took 0.8176 seconds                                         => 1000
   

5. 通过步骤3再次添加几天的数据

   xxxxxxxxxx
   Date d = tDataMaker.getDate("20220121");
   Date d = tDataMaker.getDate("20220122");
   Date d = tDataMaker.getDate("20220123");
   Date d = tDataMaker.getDate("20220124");
   Date d = tDataMaker.getDate("20220125");
   

6. 并最后查看数据条数是否正确（是否6000条数据）。

   xxxxxxxxxx
   hbase(main):009:0> count 'eventlog'
   Current count: 1000, row: 1642694315000_66495598           Current count: 2000, row: 1642780742000_28406101           Current count: 3000, row: 1642867109000_15923104           Current count: 4000, row: 1642953429000_64634226           Current count: 5000, row: 1643039962000_60757724           Current count: 6000, row: 1643126314000_96910349           6000 row(s)
   Took 1.7187 seconds                                         => 6000
