Before you begin reading this guide, we recommend you try running the Elasticsearch Error Check-Up which can resolve issues that cause many errors.

This guide will help you check for common problems that cause the log ” Cannot notify file changes listener ” 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: discovery-file.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).

         private void onFileChanged() {
            for (FileChangesListener listener : listeners()) {
                try {
                    listener.onFileChanged(file);
                } catch (Exception e) {
                    logger.warn("cannot notify file changes listener"; e);
                }

            }
        }
