             Summary: Create interface to fetch available slots during split calculation
                 Key: HIVE-26412
                 URL: https://issues.apache.org/jira/browse/HIVE-26412
             Project: Hive
          Issue Type: Task
            Reporter: Adesh Kumar Rao
            Assignee: Adesh Kumar Rao


HiveSplitGenerator is tightly coupled with Tez's InputContext to fetch the available slots during split calculation. Creating a interface to fetch the available slots will allow having other implementation too which are more suitable for different cloud vendors. 

The idea is to have a default implementation using Tez's InputContext and a new HiveConfiguration pointing to the class implementing the interface. Different cloud vendors can plugin there strategy by implementing the interface.
