> The Ambari LogSearch integration layer is currently creating too many
> repeated error log messages in ambari-server.log when a connection attempt
> fails.
> Hundreds of instances of the following log message:
> {code}
> 2016-04-20 14:57:13,000 ERROR qtp-ambari-client-324
> LoggingSearchPropertyProvider - Error occurred while making request to
> LogSearch service, unable to populate logging properties on this resource
> {code}
> appear when a connection attempt to the LogSearch service fails.
> This problem can occur when:
> 1. The LogSearch service crashes or is unexpectedly brought down
> 2. There is a lag time during which a crashed service is still considered to
> be in the STARTED state, which is the state checked by the
> LoggingSearchPropertyProvider to determine if a connection should be
> attempted.
> 3. This causes the LogSearch integration code to log many connection attempt
> failures un-necessarily, since only one instance of this message is
> necessary.
> The LogSearch integration code should use a static counter to determine how
> many times a given error log should appear.
> I'm working on a fix for this, and will submit a patch shortly.
