--------------------------------------
Summary: Set up generic puppet module architecture to manage both
HDP and CDH (and Apache?) stacks
Key: AMBARI-3524
URL: https://issues.apache.org/jira/browse/AMBARI-3524
Project: Ambari
Issue Type: Improvement
Components: agent
Reporter: Thibaut Marmin
Currently ambari-agent manages stacks via puppet modules. These modules are
specific to HDP stacks in the sens that scripts strongly depend on it special
features:
- Some packages only exists in HDP stack (e.g. hadoop-sbin, hadoop-pipes, etc.)
- Some scripts doesn’t exists in CDH stack (e.g.
/usr/lib/hadoop/bin/hadoop-daemon.sh)
- Etc.
To allow ambari to manage CDH stacks, two ways are possible according to my
point of view :
- Consider CDH services as new services. This includes development of new
puppet modules named cdh instead hdp.
- Make the current puppet modules more generic by removing all hdp references
in their names and develop an additional conditional level to handle cases as
you deploy CDH or HDP stack.
The second method seems to be more attractive because it abstracts the tool
from HDP naming.
