Or

create view elb_raw_log_detailed
as
select request_date, elbname, requestip, requestport, backendip, backendport, requestprocessingtime,
backendprocessingtime, clientresponsetime, elbresponsecode, backendresponsecode, receivedbytes,
sentbytes, requestverb, url, parse_url(url, 'QUERY','aid') as aid, parse_url(url, 'QUERY','tid')

Guys,

I am struggling to create this view. I am keep getting the error in bold. I found that I need
to use lateral view but still I am not able to get the syntax right.

hive> create view elb_raw_log_detailed as select request_date, elbname, requestip, requestport,
backendip, backendport, requestprocessingtime, backendprocessingtime, clientresponsetime,
elbresponsecode, backendresponsecode, receivedbytes, sentbytes, requestverb, url, parse_url_tuple(url,
'QUERY:aid') as aid, parse_url_tuple(url, 'QUERY:tid') as tid, parse_url_tuple(url, 'QUERY:eid')
as eid, parse_url_tuple(url, 'QUERY:did') as did, protocol, useragent, ssl_cipher, ssl_protocol
from elblogz;

FAILED: SemanticException [Error 10081]: UDTF's are not supported outside the SELECT clause,
nor nested in expressions

Yes views looks like a way to go

The royal way to do that is a view IMHO.

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'

          "input.regex" = "([^ ]*) ([^ ]*) ([^ ]*):([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;

Guys,

I want to get the field of elb logs. A sample elb log is given below and I am using below
create table definition. It is working fine. I am getting what I wanted but now I want the
bold part as well. For example eid, tid, aid. Can anyone help me how can I match them as well.

NOTE: The position of aid, eid, tid is not fixed and it may change.
