当我试图将存储在mysql数据库中的表存储到我的HDFS中时,
sqoop导入--连接jdbc:mysql://hostname1.com/mydb --用户名user1 --密码pwd1 -table emp1;

我在CDH6集群上创建了一个orc文件。在这个orc文件的顶部创建了hive表。此表也是从presto使用presto单元连接器查询的。Presto安装在同一个CDH6集群上。当从presto_cli v/s hive_cli查询数据时会注意到时间差。单元-orcfiledump和单元查询都将时间戳列值返回为2021-11-08 15:09:50。
hive> select event_time from icampaign_message_history_dm where bintime=1636383600;
