Log Context

Log “[{}] adding index {}; preferred over [{}]” classname is TribeService.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                             // on conflict; prefer a tribe...
                            String preferredTribeName = onConflict.substring(ON_CONFLICT_PREFER.length());
                            if (tribeName.equals(preferredTribeName)) {
                                // the new one is hte preferred one; replace...
                                clusterStateChanged = true;
                                logger.info("[{}] adding index {}; preferred over [{}]"; tribeName; tribeIndex.getIndex();
                                        existingFromTribe);
                                removeIndex(blocks; metaData; routingTable; tribeIndex);
                                addNewIndex(tribeState; blocks; metaData; routingTable; tribeIndex);
                            } // else: either the existing one is the preferred one; or we haven't seen one; carry on
                        }
