Vitalii Diravka updated DRILL-6454:
-----------------------------------
Description:
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);
