--------------------------------------------
Summary: Support ordered component installs.
Key: AMBARI-12002
URL: https://issues.apache.org/jira/browse/AMBARI-12002
Project: Ambari
Issue Type: Improvement
Affects Versions: 2.0.0
Environment: HDP2.2, RHEL6
Reporter: Christopher Jackson
When defining a custom service it may involve a component which needs to modify
another component. As such the order in which components install becomes
important. This could be achieved by looking at the list of dependencies for a
given component. It should enforce that all components listed as dependencies
with a scope of host are installed prior to the given component.
Per Sumit Mohanty, 'Its easy to implement an install order as well - basically
call the same helper method as done for START.'
In my use case I have CUSTOM_SERVICE/CUSTOM_CLIENT that has a scope:host
dependency on HDFS/HDFS_CLIENT and HBASE/HBASE_CLIENT, I would expect
HDFS_CLIENT and HBASE_CLIENT to install before CUSTOM_CLIENT.
