Question

我有一个包含create table语句的HQL文件。

CREATE TABLE IF NOT EXISTS employee ( eid int, name String,
salary String, destination String)
COMMENT 'Employee details'
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '^A'
LINES TERMINATED BY '\n'
STORED AS TEXTFILE;

表的字段分隔符是/ u0001（ctrl-A）。当我使用hive（hive-f）运行这个hql文件时，它工作得很好。但是当我使用beeline运行时，我是获得解析异常

[cloudera@quickstart Desktop]$ beeline -u jdbc:hive2://quickstart:10000/default -n admin -d org.apache.hive.jdbc.HiveDriver -f createtable.hql

Error: Error while compiling statement: FAILED: ParseException line 5:0 cannot recognize input near ''FIELDS TERMINATED BY '' 'LINES' 'TERMINATED' in serde properties specification (state=42000,code=40000)

好像beeline shell无法正确解析不可打印的字符（ctrl a）。但是hive客户端没有任何问题

任何帮助将不胜感激

使用以下选项之一：

... fields terminated by '\001' (Octal)
... fields terminated by '1' (Decimal)
... fields terminated by '\u0001' (Hexadecimal)

请注意，有一个与Unicode文字（'\ u0001'）相关的错误，假设要在2.1版中修复，因此使用第3个选项不适用于早期版本。 https://issues.apache.org/jira/browse/HIVE-13434
