> 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 implement new GroupScan operators for interpreting HiveScan as MapRDBGroupScan;
> - to add storage planning rule to convert HiveScan to MapRDBGroupScan;
> - to add system/session option to enable using of this native reader;
> - to create a new module for the rule and scan operators, which will be compiled and build only for mapr profile (there is no reason to leverage it for default profile);
