--------------------------------------

             Summary: Native MapR DB plugin support for Hive MapR-DB json table
                 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
             Fix For: 1.14.0


Hive can create and query MapR-DB tables via maprdb-json-handler.
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);
