Log Context

Log “Running DELETE Index on [” classname is TransportDeleteJobAction.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

         ActionListener customIndexSearchHandler = ActionListener.wrap(
                searchResponse -> {
                    if (searchResponse == null || searchResponse.getHits().totalHits > 0) {
                        deleteByQueryExecutor.onResponse(true); // We need to run DBQ and alias deletion
                    } else {
                        logger.info("Running DELETE Index on [" + String.join("; "; indexNames.get()) + "] for job [" + jobId + "]");
                        DeleteIndexRequest request = new DeleteIndexRequest(indexNames.get());
                        request.indicesOptions(IndicesOptions.lenientExpandOpen());
                        // If we have deleted the index; then we don't need to delete the aliases or run the DBQ
                        executeAsyncWithOrigin(
                                parentTaskClient.threadPool().getThreadContext();
