> Key: DRILL-6454
> URL: https://issues.apache.org/jira/browse/DRILL-6454
> Project: Apache Drill
> Issue Type: New Feature
> Components: Storage - Hive, Storage - MapRDB
> Affects Versions: 1.13.0
> Reporter: Vitalii Diravka
> Assignee: Vitalii Diravka
> Priority: Major
> Labels: doc-impacting
> Fix For: 1.14.0
>
>
> Hive can create and query MapR-DB tables via maprdb-json-handler:
> https://maprdocs.mapr.com/home/Hive/ConnectingToMapR-DB.html
> The aim of this Jira to implement Drill native reader for Hive MapR-DB tables
> (similar to parquet).
> Design proposal is:
> - to use JsonTableGroupScan instead of HiveScan;
> - to add storage planning rule to convert HiveScan to MapRDBGroupScan;
> - to add system/session option to enable using of this native reader;
> - native reader can be used only for Drill build with mapr profile (there is
> no reason to leverage it for default profile);
