Description

Starting implementation of Storage Handler for Druid.

First assuming the data already sits in Druid. We will allow users to declare a table in Hive that references a datasource in Druid.

The proposed syntax is as follows:

CREATE TABLE druid_table_1
STORED BY 'org.apache.hadoop.hive.druid.DruidStorageHandler'
TBLPROPERTIES ("druid.datasource" = "xyz");

For the statement above, the Druid datasource that we want to query is xyz.

The schema of the new table is discovered automatically issuing a SegmentMetadata to Druid that will retrieve the names and types of the columns present in the datasource.
