[jira] [Created] (HIVE-19201) Hive doesn't read Druid data correctly

Tournadre created HIVE-19201:
--------------------------------

             Summary: Hive doesn't read Druid data correctly
                 Key: HIVE-19201
                 URL: https://issues.apache.org/jira/browse/HIVE-19201
             Project: Hive
          Issue Type: Bug
          Components: Druid integration, Hive
    Affects Versions: 2.3.0
         Environment: Ubuntu 16.4 TLS Desktop
Druid 0.12.0 (StandAlone - Quickstart conf)
Hive 2.3.0 (StandAlone - Quickstart conf)

Also have Hadoop and Zookeeper running
            Reporter: Tournadre


I created an external table on hive pointing at my datasource : wikiticker on druid (I already defined the broker adress). However few colums appear as NULL without knowing why.

I have also many time *.lck file in the metadatadb on Hive and Druid to delete (otherwise, queries don't work)

So the describe statement lists the column and their type correctly, however I only get "NULL" when I query some column (string type). I checked in my Druid, the data are still here.

 

Help ! :(  

PS : Sorry first issue and JIRA, didn't see my issue resolved yet.
