only supports newline '\n' right now. Error encountered near token ''
意思是：仅支持‘\n’ 分隔符
我写的分隔符方式
row format delimited
fields terminated by '\001'
collection items terminated by '\002'
map keys terminated by '\003'
lines terminated by ''
NULL defined as ''
正确写法：
row format delimited
fields terminated by '\001'
collection items terminated by '\002'
map keys terminated by '\003'
lines terminated by '\n'
NULL defined as ''
ASCII码中的序号为1，所以可以用'\001'表示
