-------------------------------------
Summary: Add Weighted Driver selector for selecting driver among
hive and spark drivers
Key: LENS-661
URL: https://issues.apache.org/jira/browse/LENS-661
Project: Apache Lens
Issue Type: Sub-task
Components: driver-hive
Reporter: Raju Bairishetti
Spark Driver also uses hive thrift server as an execution engine. Both spark
and hive drivers are eligible for executing the same cube query. Right now,
Jdbc has Query cost 0.0 and Hive driver has 1.0. Spark driver also uses same
query cost as hive driver which is 1.0.
We can introduce a weighted driver selector which will submit configured % of
queries to spark driver for execution.
