> Key: AMBARI-17811
> URL: https://issues.apache.org/jira/browse/AMBARI-17811
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.4.0
> Reporter: Robert Nettleton
> Assignee: Robert Nettleton
> Priority: Critical
> Fix For: 2.4.0

> Attachments: AMBARI-17811.patch

> Original Estimate: 24h
> Remaining Estimate: 24h
>
> The LogSearch integration in the Ambari REST layer uses a "searchEngine"
> interface to abstract out the calls to the LogSearch Server, in order to
> handle search query requests.
> If LogSearch is not running, and a REST GET call is made on the following
> Ambari resource:
> {code}clusters/$CLUSTER_NAME/logging/searchEngine{code}
> The following NullPointerException will be thrown in ambari-server.log:
> {code}
> java.lang.NullPointerException
> at
> org.apache.ambari.server.api.services.LoggingService.handleDirectRequest(LoggingService.java:113)
> at
> org.apache.ambari.server.api.services.LoggingService.getSearchEngine(LoggingService.java:76)
> at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
> {code}
> The Ambari LogSearch integration should handle this type of failure more
> gracefully. In the event that this REST resource is accessed when LogSearch
> is not running, or is not deployed, then a check for a null
> LoggingRequestHelper should be implemented, and a reasonable error message
> returned to the caller, to indicate that the "searchEngine" resource is not
> currently available.
> I'm working on a fix for this, and will be submitting a patch shortly.
