-----------------------------------------
Summary: Command execution by single python executor.
Key: AMBARI-16217
URL: https://issues.apache.org/jira/browse/AMBARI-16217
Project: Ambari
Issue Type: Task
Components: ambari-server
Reporter: Sebastian Toader
Fix For: 2.4.1
Currently, all commands are executed via own python executor - either serially
or in parallel. Instead, a single python executor can be created to execute all
commands. When all commands are combined, then one execution of
before-install/start and after-install/start would suffice. In addition, all
starts can be called in parallel while configure can be serialized where there
are shared resources.
