Juanjo Marron commented on AMBARI-14435:
----------------------------------------
Added AMBARI-14435.patch
This patch removes the hardcoded stack versions in ZK common-services code
(centralized version and parameterized stack configurations will be faced in
other JIRAS)
stack_features is now a property in .json format in
configuration/cluster-env.xml for each stack version.
With the structure:
{
"stack_features": [
{ "name": "feature1", "description" : "Feature1 support", "min_version" :
"Y.Y.Y.Y" , "max_version" : "X.X.X.X"}
,
...
]
}
where min_version/max_version are optional constraints.
New resource_management/libraries/functions/stack_fetaures.py has been
introduced to parse the json file and called from service code to check if the
stack supports the required feature.
