When the LogSearch Integration layer in Ambari cannot obtain the logsearch logging metadata for a given HostComponent, it logs the following message to ambari-server.log:
The problem is that this message is logged too many times at the WARN level, without providing much useful information. In the case of a larger cluster, this message may be logged thousands of times in the ambari-server.log, and was caused by the fact that SmartSense IDs do not exist for LogSearch, since they haven't been added to the separate SmartSense stack definition.
This issue should be fixed with the following two minor changes:
1. This message should be logged at the DEBUG level, since it is generally only useful when a particular component's log messages cannot be found.
2. This message should be modified to include the Host and Component associated with the LogSearch error, to assist in debugging if this situation occurs.
