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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
