Hi Sungoo,
get_splits() is used by the HiveWarehouseConnector, you can see an example
here:
https://github.com/hortonworks/hive-warehouse-connector/blob/HDP-3.1.5.20-4-tag/src/main/java/com/hortonworks/spark/sql/hive/llap/HiveWarehouseDataSourceReader.java
That being said, I'm not sure if this UDF is technically supported as a
public API by the Hive community, so you may want to check about that.
