[jira] [Updated] (DRILL-792) Joining a hive table with parquet file
is returning an empty result set
[ https://issues.apache.org/jira/browse/DRILL-792?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rahul Challapalli updated DRILL-792:
------------------------------------
Component/s: Storage - Parquet
Description:
git.commit.id.abbrev=70fab8c
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.
