-------------------------------------
Summary: Ambari should add warning when LogSearch selected without
Ambari-Infra
Key: AMBARI-19441
URL: https://issues.apache.org/jira/browse/AMBARI-19441
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.5.0
Reporter: Andrii Tkach
Assignee: Andrii Tkach
Priority: Critical
Fix For: 2.5.0
That issue demonstrates that is is possible, during a UI cluster deployment, to
select "LogSearch" as a service, but not select "Ambari-Infra". The UI then
continues through the wizard, without requiring any additional LogSearch
configuration.
LogSearch has been updated to allow for external SolrCloud deployments as well
as internally-managed SolrCloud deployments, so the original dependency in the
stack had to be removed to support this deployment mode.
That being said, the default behavior in the UI deployment should still
encourage most users to accept the default behavior, meaning that the
Ambari-Infra service should be included.
Currently, if Ambari-Infra is not selected, the deployment will fail, since the
wizard does not require either selecting Ambari-Infra or configuring the
location of the external SolrCloud instance.
I ran a test by selecting Atlas without selecting Ambari-Infra (which is a
similar deployment case, since Atlas can use an internal or external SolrCloud
deployment), and found that in the Atlas case the UI pops up a "Limited
Functionality Warning" if Ambari-Infra is not selected.
We should implement this for LogSearch as well, so that if the user selects
LogSearch, but does not select Ambari-Infra, then a LogSearch-specific limited
functionality warning pops up, to let the user know that this is not default
scenario, and will require further configuration.
This work would involve two tasks:
1. If the user selects LogSearch, then Ambari-Infra should be auto-selected by
default.
2. Adding the "Limited Warning Functionality" popup to the wizard, if LogSearch
is selected without Ambari-Infra.
3. If the user receives this popup and chooses to proceed anyway, the
configuration wizard should enforce the configuration of the external SolrCloud
instance.
I took a quick look at the ambari-web code, and it looks like something similar
to #2 is implemented in the step4_controller.js:
{code}
var atlasService = this.findProperty('serviceName', 'ATLAS');
var ambariInfraService = this.findProperty('serviceName', 'AMBARI_INFRA');
if (atlasService && atlasService.get('isSelected') && ambariInfraService &&
!ambariInfraService.get('isSelected')) {
this.serviceValidation(callback, 'AMBARI_INFRA', 'ambariInfraCheck');
}
{code}
It's likely that we can reuse this approach for LogSearch as well.
