过滤hive复杂数据类型

Question

我使用hive创建了一个表，我希望过滤数据

create table student(
      id bigint
     ,name string
     , course array<string>)
ROW FORMAT DELIMiTED fields terminated by '\t'
collection items terminated by ','
STORED AS TEXTFILE;

和

之类的数据

100 student1    java,.net,hadoop
101 student2    .net,hadoop
102 student3    java,hadoop
103 student4    .net,hadoop
104 student5    java,.net
105 student6    java,.net,hadoop
106 student7    .net,hadoop

  

适合这个数据基于cource = hadoop

请有人帮助我。
