Viraj Jasani updated AMBARI-25240:
----------------------------------
Description:
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.
Before starting off with Rolling Upgrade, we can update "cluster-env" config
with property key: "max_degree_parallelism". If the value of this key is
integer, that value will be selected as Batch Size. If not, then the default
behavior will continue.
