Subject [jira] [Updated] (HIVE-15046) Multiple fixes for Druid handler
Date Wed, 26 Oct 2016 03:46:58 GMT

     [ https://issues.apache.org/jira/browse/HIVE-15046?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jesus Camacho Rodriguez updated HIVE-15046:
-------------------------------------------
    Description: 
- Druid query type not recognized after Calcite upgrade; introduced by HIVE-13316.
- Fix handling of NULL values for GroupBy queries.
- Fix handling of dimension/metrics names, as those names in Druid are case sensitive.
- Select Druid query to effectively return no rows when the result is empty (previously returning
a single row).
- When it is split, each of the parts of a Select query might return more results than threshold;
set threshold to max integer in query so we do not face this problem.

  was:Introduced by HIVE-13316.
