Briefly, this error occurs when Elasticsearch tries to update the fetch timeout value but encounters an issue. Fetch timeout is the time allowed for a fetch request to be completed. This could be due to incorrect configuration settings or network issues. To resolve this, you can try increasing the fetch timeout value in the Elasticsearch configuration file. Alternatively, check your network connectivity and ensure that there are no issues that could be causing delays. Lastly, ensure that your Elasticsearch cluster has sufficient resources to handle the requests.

Log Context

Log “updating fetch timeout [{}] from [{}] to [{}]” classname is InternalClusterInfoService.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :


            TimeValue newFetchTimeout = settings.getAsTime(INTERNAL_CLUSTER_INFO_TIMEOUT; null);
            if (newFetchTimeout != null) {
                logger.info("updating fetch timeout [{}] from [{}] to [{}]"; INTERNAL_CLUSTER_INFO_TIMEOUT; fetchTimeout; newFetchTimeout);
                InternalClusterInfoService.this.fetchTimeout = newFetchTimeout;

            // We don't log about enabling it here; because the DiskThresholdDecider will already be logging about enable/disable
