twitter - Cloudera Twiiter Hive Query failure -

-

team,

curious know if succeeded in executing query twitter cloudera example?

i added mentioned serde jar in beewax file resources jar, still getting error query.

query:

select t.retweeted_screen_name, sum(retweets) total_retweets, count(*) tweet_count (select retweeted_status.user.screen_name retweeted_screen_name, retweeted_status.text, max(retweet_count) retweets tweets group retweeted_status.user.screen_name, retweeted_status.text) t group t.retweeted_screen_name order total_retweets desc limit 10;

your query has following error(s):

error while processing statement: failed: execution error, return code 2 org.apache.hadoop.hive.ql.exec.mr.mapredtask

resolved!

don't use prebuilt serde jar download. may outdated.

compile yourself!
