如何将一个Hive表的特定分区加载到没有分区的另一个Hive表中?

[英]How to load a particular partition of a Hive table into another Hive table with no partitions?

HiveTable1 has columns name, email in partition date=12/12/2014 There are other date partitions in the table as well. HiveTable1列名称为,电子邮件的分区date=12/12/2014 。表中还包含其他日期分区。

HiveTable2 is created with name, email columns. HiveTable2是使用名称和电子邮件列创建的。

How do I transfer the data from HiveTable1 to HiveTable2? 如何将数据从HiveTable1传输到HiveTable2?

If you just filter on a single value for the partition key then it will only load that partition. 如果仅对分区键的单个值进行过滤,则它将仅加载该分区。

INSERT INTO TABLE HiveTable2
SELECT name, email FROM HiveTable1 WHERE date="12/12/2014";
