[jira] [Created] (HIVE-17927) Pre-Warm Spark Driver

Sahil Takiar created HIVE-17927:
-----------------------------------

             Summary: Pre-Warm Spark Driver
                 Key: HIVE-17927
                 URL: https://issues.apache.org/jira/browse/HIVE-17927
             Project: Hive
          Issue Type: Improvement
          Components: Spark
            Reporter: Sahil Takiar


Hive-on-Spark has an option to pre-warm executors, it would be good to have an option to pre-warm the HoS driver.

Basically, submit the HoS application as soon as possible, rather than waiting until a query is ready to be submitted. This can help startup time for the first query run in a HoS session. The application can be setup in the background while queries are being compiled.
