Before you read this guide, we recommend you run the Elasticsearch Error Check-Up which detects issues in ES causing log errors (free tool that requires no installation). 

This guide will help you check for common problems that cause the log “Failed node ” + nodeId + “” 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: node.

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 discover the cause of many errors and provides suitable actionable recommendations how to resolve them (join over 700 users who use this free tool).

Log Context

Log”Failed node [” + nodeId + “]”classname  is TransportTasksAction.java We extracted the following from Elasticsearch source code for those seeking an in-depth context :

private void onFailure(int idx; String nodeId; Throwable t) {
  if (logger.isDebugEnabled() && !(t instanceof NodeShouldNotConnectException)) {
  logger.debug(new ParameterizedMessage("failed to execute on node [{}]"; nodeId); t);
  }
 
  responses.set(idx; new FailedNodeException(nodeId; "Failed node [" + nodeId + "]"; t));
 
  if (counter.incrementAndGet() == responses.length()) {
  finishHim();
  }
  }
