【原】创建Hive表，分号分隔符“；”引起的异常

【障碍再现】

在创建支持Map数据结构的Hive表时，抛出如下异常

hive> create table tab_map(name string,info map<string,string>)
    > row format delimited
    > fields terminated by '\t'
    > collection items terminated by ';'
    > map keys terminated by ':';

【原因分析】
主要原因是定义字段分割符的时候用了";"作为字段分隔符，而HDFS文件的的格式就是用分号隔开的，因此，相互冲突。

【解决方案】
找到分号的asc码值： http://blog.csdn.net/lxpbs8851/article/details/11525501
（其他字符有同样问题也可以这样做）找到的是073 那么将定义表的语句修改为：
row format delimited fields terminated by '73'。

最初的建表代码：

create table tab_map(name string,info map<string,string>)
row format delimited
fields terminated by '\t'
collection items terminated by ';'   <---- 注意此处
map keys terminated by ':';

解决问题后的代码：

create table tab_map(name string,info map<string,string>)
row format delimited
fields terminated by '\t'
collection items terminated by '73'         <------注意此处
map keys terminated by ':';
