When was the last time you measured? > Ambari agent support for parallel task execution during deployment > ------------------------------------------------------------------ > > Key: AMBARI-8189 > URL: https://issues.apache.org/jira/browse/AMBARI-8189 > Project: Ambari > Issue Type: Task > Affects Versions: 2.0.0 > Reporter: Ivan Mitic > Assignee: Ivan Mitic > Fix For: 2.1.0 > > Attachments: AMBARI-8189.2.patch, AMBARI-8189.patch > > > Ambari serializes all operations on the node, and by actually parallelizing the independent setup activities, deployment time would significantly decrease. Ambari stack definition already defines a notion of service dependencies, so some basic infra requirements for parallel execution are already in place. > This is a tracking Jira where we can discuss this proposal and work on the design/prototype and patch. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
