Hello,
--Pig 0.10.0--
I'd like to access straitght forward to the result of:
grunt> c = foreach logs generate REGEX_EXTRACT_ALL(f1, '([a-zA-Z]{3,3})
([0-9]{1,2}) ([0-2]{1}[0-9]{1}:[0-5]{1}[0-9]{1}:[0-5]{1}[0-9]{1})
([a-zA-Z0-9-_]+) ([a-zA-Z]+)\\[[0-9]+\\]: (.*)');
grunt> illustrate c;
-------------------------------------------------------------------------------------------------------------
| logs |
f1:chararray
|
-------------------------------------------------------------------------------------------------------------
| | Feb 24 20:09:01 hadoop-master CRON[3574]:
pam_unix(cron:session): session closed for user root |
-------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------
| c | org.apache.pig.builtin.regex_extract_all_f1_178:tuple() |
----------------------------------------------------------------------------
| | (Feb, ..., pam_unix(cron:session): session closed for user root) |
----------------------------------------------------------------------------
but the only way I found is to save&reload it:
grunt> store c into 'pig/AUTH.result';
grunt> auth = LOAD 'pig/AUTH.result/part-m-00000' USING PigStorage(',')
AS (m:chararray, d:int, time:chararray, hostname:chararray,
service:chararray, info:chararray);
grunt> day_frequency = GROUP auth by (d,service);
...
is there a way to name the tuple items or to access them such as c.$0 or
FLATTEN(c).$0.... ??
Thanks,
Brice
