如何使用Hive插入表选择函数查询

Question

插入表格当选择具有功能结果值的表格时，不会显示该值。我该怎么办？

• 功能查询结果

  MongoDB Exception – yii\mongodb\Exception
  no such cmd: listCollections
  
  Caused by: MongoDB\Driver\Exception\RuntimeException
  no such cmd: listCollections
  
  in /var/www/html/advanced/vendor/yiisoft/yii2-mongodb/Command.php at line 187
  

• 插入函数查询查询结果时

  hive> SELECT start_num,geoip(start_ip,'COUNTRY_CODE','/usr/local/hive/lib/GeoLite2-Country.mmdb') from geoip limit 3;
  OK
  17/05/24 18:02:15 INFO mapred.FileInputFormat: Total input files to process : 1

• iptest2 table desc

  Query insert into table iptest2 SELECT start_num,geoip(start_ip,'COUNTRY_CODE','/usr/local/hive/lib/GeoLite2-Country.mmdb') from geoip limit3;
