----------------------------------------
Summary: Allow default value of number of parallel tasks run
during Upgrade to be customizable
Key: AMBARI-23127
URL: https://issues.apache.org/jira/browse/AMBARI-23127
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Siddharth Wagle
Assignee: Siddharth Wagle
Fix For: 2.6.2
On large clusters of 1000+ nodes the default value of 100 for max degree of
parallelism results in Stop and Start command batches of 100 hosts and
resulting operation taking longer because of the default batch size. This Jira
adds a possible override through ambari.properties.
Property:
{\{stack.upgrade.default.parallelism}}
