This guide will help you check for common problems that cause the log ” Incompatible cluster state version resending complete cluster state ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: cluster, discovery and version.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up to analyze Elasticsearch configuration and help resolve this error.

Log Context

Log “incompatible cluster state version – resending complete cluster state” classname is LocalDiscovery.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                         }
                        try {
                            newNodeSpecificClusterState = discovery.lastProcessedClusterState.readDiffFrom(StreamInput.wrap(clusterStateDiffBytes)).apply(discovery.lastProcessedClusterState);
                            logger.trace("sending diff cluster state version [{}] with size {} to [{}]"; clusterState.version(); clusterStateDiffBytes.length; discovery.localNode().getName());
                        } catch (IncompatibleClusterStateVersionException ex) {
                            logger.warn("incompatible cluster state version - resending complete cluster state"; ex);
                        }
                    }
                    if (newNodeSpecificClusterState == null) {
                        if (clusterStateBytes == null) {
                            clusterStateBytes = Builder.toBytes(clusterState);
