-----------------------------------
Summary: Services with invalid themes hang the UI when you attempt
to add them
Key: AMBARI-18765
URL: https://issues.apache.org/jira/browse/AMBARI-18765
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: trunk, 2.4.0, 2.5.0
Reporter: Tim Thorpe
Assignee: Tim Thorpe
Fix For: trunk, 2.5.0, 2.4.2
For a given service if the theme.json file is not properly formatted, Ambari
server will still start 'successfully' but attempts to add that service to the
cluster will fail.
The Ambari server start will log the theme error. Although it neglects to
mention which theme file and service are in error.
When you attempt to add the service, it will query for the service's themes:
api/v1/stacks/<stack>/versions/<version>/services?StackServices/service_name.in(HDFS,YARN,MAPREDUCE2,ZOOKEEPER,RANGER,RANGER_KMS,SLIDER)&themes/ThemeInfo/default=true&fields=themes/*
This will return something like the following for the invalid theme:
"ThemeInfo" : {
"default" : true,
"file_name" : "theme_version_2.json",
"service_name" : "RANGER_KMS",
"stack_name" : "BigInsights",
"stack_version" : "4.3",
"theme_data" : null
}
where the theme_data is null.
