Subject Re: ELB Log processing
Date Tue, 20 Sep 2016 10:14:20 GMT
Thanks for the reply Damien. The suggestion you gave is really useful.
Currently I am achieving my desired output by performing below steps. But I
want to achieve the desired result in one step instead of two. Do we have
any way so that I can get the aid, did etc in create table statement? If
not I will have to look for the option that you mentioned

1.
CREATE TABLE elblog (
Request_date STRING,
      ELBName STRING,
      RequestIP STRING,
      RequestPort INT,
      BackendIP STRING,
      BackendPort INT,
      RequestProcessingTime DOUBLE,
      BackendProcessingTime DOUBLE,
      ClientResponseTime DOUBLE,
      ELBResponseCode STRING,
      BackendResponseCode STRING,
      ReceivedBytes BIGINT,
      SentBytes BIGINT,
      RequestVerb STRING,
      URL STRING,
      Protocol STRING,
Useragent STRING,
ssl_cipher STRING,
ssl_protocol STRING
)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.RegexSerDe'
WITH SERDEPROPERTIES (
          "input.regex" = "([^ ]*) ([^ ]*) ([^ ]*):([0-9]*) ([^
]*):([0-9]*) ([.0-9]*) ([.0-9]*) ([.0-9]*) (-|[0-9]*) (-|[0-9]*) ([-0-9]*)
([-0-9]*) \"([^ ]*) ([^ ]*) (- |[^ ]*)\" \"(.*)\" (.*) (.*)$"
)
STORED AS TEXTFILE;

2.
create table elb_raw_log as select request_date, elbname, requestip,
requestport, backendip, backendport, requestprocessingtime,
backendprocessingtime, clientresponsetime, elbresponsecode,
backendresponsecode, receivedbytes, sentbytes, requestverb, url,
regexp_extract(url, '.*aid=([a-zA-Z0-9]+).*', 1) as aid,
regexp_extract(url, '.*tid=([a-zA-Z0-9]+).*', 1) as tid,
regexp_extract(url, '.*eid=([a-zA-Z0-9]+).*', 1) as eid,
regexp_extract(url, '.*did=([a-zA-Z0-9]+).*', 1) as did, protocol,
useragent, ssl_cipher, ssl_protocol from elblog;
