-------------------------------------
Summary: Dynamically update Rolling Upgrade batch size
Key: AMBARI-25240
URL: https://issues.apache.org/jira/browse/AMBARI-25240
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Affects Versions: trunk, 2.6.2, 2.7.4
Reporter: Viraj Jasani
Assignee: Viraj Jasani
We have a default value 100 for Rolling Upgrade batch size. In order to modify
that size, upgrade.xml should have <max-degree-of-parallelism> or stack should
define it.
However, we can provide a way to update the batch size dynamically using some
config that can be updated by client using Rest API and subsequent Rolling
Upgrade can get the updated batch size from the config.
