can anyone tell me why the following won't work
i have bags like this:
x:
(utm_source,3)
(sprint_&utm_medium,3)
(banner&utm_campaign,3)
(sprint,3)
i wanna filter out all the bags with 'utm' included and get the last one
(sprint, 3),
this is what i used:
y = FILTER x BY REGEX_EXTRACT($0, '(.*)utm(.*)', 0) == null;
this one return nothing;
y = FILTER x BY REGEX_EXTRACT($0, '(.*)utm(.*)', 0) is null;
this one return:
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1000: Error during parsing.
Encountered " "is" "is "" at line 1, column 53.
Was expecting one of:
"parallel" ...
"and" ...
"or" ...
";" ...
please help!
