Question

我正在尝试将记录插入到我创建的表中。但是它失败，并显示FailedPredicateException（

我尝试对select语句使用别名，然后在sql中使用列名，但由于相同的错误而失败。可能是什么问题？

create table sales_log(
trxn_uuid string,
unit_sold int,
unihprice decimal(13,4),
event_ts timestamp
)
stored as orc
location '/user/me/sales/sales_log';

insert into sales_log select 'axxx1', 2, 8,cast('2018-01-01 06:34:56.789' as timestamp);

hive> insert into sales_log select 'axxx1', 2, 8,cast('2018-01-01 06:34:56.789' as timestamp);

已知问题，已在Hive 1.3.1 / 2.0中修复。

在早期版本中，如果没有insert as select子句，则不能使用from。使用插入into ... values ...重写查询或升级到最新的Hive版本。

为什么将记录插入到配置单元中失败，并显示FailedPredicateException？
