I need alternative query for the below query.
Select a.name,max(a.cnt) from (Select name,count(name) as cnt from candidate group by name) a group by a.name order by 2 desc limit 1;
drop table if exists candidate;
create external table candidate(name string) stored as textfile LOCATION '/user/cloudera/test/Exercise/candidate'
load data inpath '/user/cloudera/test/candidate' overwrite into table candidate;
Sample data:
raja
raja
raja
raja
raja
Anil
Anil
Anil
Anil
Anil
Anil
Anil
Giri
Giri
Giri
mahe
mahe
I need result which name is repeated more time. As per example above example
Anil repeated more.
To achieve the result I wrote the below query.But I am not satisfied with this query performance does anyone have alternative for this query?
Select a.name,max(a.cnt) from (Select name,count(name) as cnt from candidate group by name) a group by a.name order by 2 desc limit 1;
Thanks Venkadesan
