--------------------------------------
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.
