Log Context

Log “Unexpected failure during [{}]” classname is TransportClusterHealthAction.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                    }

                    
Override
                    public void onFailure(String source; Exception e) {
                        logger.error(() -> new ParameterizedMessage("unexpected failure during [{}]"; source); e);
                        listener.onFailure(e);
                    }
                });
            }
        } else {
