摘要: FAILED: ParseException line 4:2 Failed to recognize predicate 'user'. Failed rule: 'identifier' in column specification 解决方法

在学习hive，创建Apache Weblog Data 访问日志表的时候出错了

CREATE TABLE apachelog (
host STRING,
identity STRING,
username STRING,
time STRING,
request STRING,
status STRING,
size STRING,
referer STRING,
agent STRING)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.RegexSerDe'
WITH SERDEPROPERTIES
("input.regex" = "([^ ]*) ([^ ]*) ([^ ]*) (-|\\[[^\\]]*\\]) (\"[^\"]*\") (-|[0-9]*) (-|[0-9]*)")
STORED AS TEXTFILE;

官方的那个建表语句有问题，上面的是修改后的，

FailedPredicateException(identifier,{useSQL11ReservedKeywordsForIdentifier()}?)

出现这个问题是因为官方user字段冲突了，吧user字段改掉就可以了！
