------------------------------------
Summary: Selecting Storm during install breaks configs (with
App.supports.appTimelineServer turned on)
Key: AMBARI-4606
URL: https://issues.apache.org/jira/browse/AMBARI-4606
Project: Ambari
Issue Type: Task
Components: client
Affects Versions: 1.5.0
Reporter: Denys Buzhor
Assignee: Denys Buzhor
Fix For: 1.5.0
During install I selected Storm service (had jobs and timeline server flags
turned on). Coming into the configurations page I hit an exception in
{{app/utils/config.js}} file's {{#tweakDynamicDefaults()}} function.
Specifically at line
{code}
if (typeof(config == "string") && config.defaultValue.indexOf("{firstHost}") >=
0)
{code}
where {{config.defaultValue}} was type boolean instead of type 'string'.
There are 2 problems here:
1. AMBARI-4287 introduced a change where global configs with default value of
string 'true' or 'false' are converted to booleans.
{code}
if (configData.displayType === 'checkbox') {
configData.value = configData.defaultValue = configData.value ===
'true'; // convert {String} value to {Boolean}
}
{code}
We should make sure that all usages of {{config.defaultValue}} account for this
change in behavior. Would be best to stay on 'string'.
2. Where the exception is thrown, the logic of the if() statement is incorrect
and should be changed to
{code}
if (typeof(config.defaultValue) == "string" &&
config.defaultValue.indexOf("{firstHost}") >= 0)
{code}
