> 1. Joining a hive table with parquet results in an empty output. Check below query
> select rankings.pageRank pagerank from `dfs/parquet/rankings/` rankings inner join hive.uservisits
uservisits on rankings.pageURL = uservisits.destinationurl
> 2. Joining hive table with hive table seems to work fine
> select rankings.pagerank pagerank from hive.rankings rankings inner join hive.uservisits
uservisits on rankings.pageurl = uservisits.destinationurl
> I attached the parquet and text files required along with the required hive ddl. Let
me know if you need more information.
