Bugs: AMBARI-20190
https://issues.apache.org/jira/browse/AMBARI-20190
Repository: ambari
Description
-------
This patch resolves AMBARI-20190.
During some larger cluster testing with LogSearch, it was discovered that a
debugging message was logged at the ERROR level, and was logged repeatedly
(thousands of times in an 800-node cluster).
This patch resolves this problem by implementing the following:
1. The ERROR message in question was moved to the DEBUG level, since it is only
generally useful in debugging situations for the integration layer.
2. The message was also updated to include the host and component name for the
resource associated with the failure, as this could be useful in future
debugging sessions when certain components aren't available via LogSearch.

Testing
-------
1. Tested manually with a 3-node vagrant cluster, to verify that the updated
log message is only available at the DEBUG level, and also that the message not
includes the host and component names when DEBUG-level logging is turned on.
2. Currently running the ambari-server unit test suite, and will update the
review with the results.
Thanks,
Robert Nettleton
