In addition to reading this guide, we recommend you run the Elasticsearch Template Optimizer to fix problems in your data modeling.

It will analyze your templates to detect issues and improve search performance, reduce indexing bottlenecks and optimize storage utilization. The Template Optimizer is free and requires no installation.

This guide will help you check for common problems that cause the log to appear. It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts below. Advanced users might want to skip right to the common problems section in each concept or run the template optimizer.

Log Context

Log “Error deleting template [{}]” classname is TemplateUpgradeService.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                 public void onFailure(Exception e) {
                    anyUpgradeFailed.set(true);
                    if (e instanceof IndexTemplateMissingException == false) {
                        // we might attempt to delete the same template from different nodes - so that's ok if template doesn't exist
                        // otherwise we need to warn
                        logger.warn(new ParameterizedMessage("Error deleting template [{}]"; template); e);
                    }
                    tryFinishUpgrade(anyUpgradeFailed);
                }
            });
        }
