[jira] [Updated] (HIVE-17362) The MAX_PREWARM_TIME should be
configurable on HoS
[ https://issues.apache.org/jira/browse/HIVE-17362?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Peter Vary updated HIVE-17362:
------------------------------
Attachment: HIVE-17362.patch
The patch contains the following changes:
- Add new configuration variable: HIVE_PREWARM_SPARK_TIMEOUT. Defaults to 5000ms to retain backward compatibility
- Enabling prewarm for q-test configurations, and setting a 4m prewarm timeout
- Removing prewarm magic from QTestUtils
Let's see it this brakes anything in the QTest framework.

> When using HIVE_PREWARM_ENABLED, we are waiting MAX_PREWARM_TIME for the containers to warm up. This is currently set to 5s. This is often not enough for a spark session to initialize the executors. We should be able to configure this, so we can set a value which has an effect.
