hive正则匹配

第一步：创建apachelog表（用于存放apache的访问日志：access_log）

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

STORED AS TEXTFILE;

第二步：插入数据：load data local inpath "/usr/local/apache/logs/access_log" into table apachelog；
