在配置单元文档中，行分隔符是 char ，因此不应接受两个字符！

row_format   : DELIMITED 
    [FIELDS TERMINATED BY char [ESCAPED BY char]]
    [COLLECTION ITEMS TERMINATED BY char]
    [MAP KEYS TERMINATED BY char] [LINES TERMINATED BY char]
    [NULL DEFINED AS char] (Note: Only available starting with Hive 0.13)

仅限当前 \n 支持。
看看这张吉拉的票。
允许以结尾的行使用其他字符
“\n”以外的行分隔符在配置单元中引发错误。
演示

hive> create table t (i int) row format delimited lines terminated by '\r\n' location '/tmp';
FAILED: SemanticException 1:64 LINES TERMINATED BY only supports newline '\n' right now. Error encountered near token ''\r\n''
