Hive错误：没有匹配的方法

Question

我在hive中执行CTAS查询，如下所述：

create table ps_agg
as select host, count(*) c, sum(l4_ul_throughput+l4_dw_throughput) usg from ops.isop
where
cast(cast(from_unixtime(begin_time) as TIMESTAMP) AS DATE) >= '2016-08-01' & 
cast(cast(from_unixtime(begin_time) as TIMESTAMP) AS DATE) < '2016-09-01'
group by host;

host, begin_time, l4_ul_throughput＆amp; l4_dw_throughput是ISOP表中的列。

我在运行此查询时收到的错误是：

Wrong arguments 'begin_time' : No matching method for class org.apache.hadoop.hive.ql.udf.UDFOPBitAnd with (string, timestamp).

begin_time是表格中的int类型。

我不知道出了什么问题。有人可以建议解决吗？

Answer 1

解决了这个问题;这是一个语法错误。

更正了语法：

create table ps_agg
as select host, count(*) c, sum(l4_ul_throughput+l4_dw_throughput) usg from ops.isop
where
cast(cast(from_unixtime(begin_time) as TIMESTAMP) AS DATE) >= '2016-08-01' AND
cast(cast(from_unixtime(begin_time) as TIMESTAMP) AS DATE) < '2016-09-01'
group by host;
