--------------------------------------
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);
