嵌套JSON蜂巢表

Question

我的JSON文件看起来像：

{VALUES:[{"UTAGID":"SYSTEM_CHILLER1","tagName":"P1","tagValue":"10","tagTime":"2015-07-23T14:29:30.731Z","tagQuality":"128"}' 
...........}]}; 

我写的JSON模式为：

create table t1(VALUES array<<struct<UTAGID:STRING, tagName:STRING, tagValue:STRING, tagTime:STRING, tagQuality:STRING>>) 

ROW FORMAT SERDE "org.apache.hadoop.hive.contrib.serde2.JsonSerde" 

STORED AS TEXTFILE; 

LOAD DATA LOCAL INPATH"/tmp/jsonstreaming.json"into table t1; 

但我仍然得到错误的ParseException的缺失<附近struct关键字。 可能是什么原因？

Answer 1

我认为你有一个额外的<尝试

create table t1(VALUES array<struct<UTAGID:STRING, tagName:STRING, tagValue:STRING, tagTime:STRING, tagQuality:STRING>>)
