Log Context

Log “onFollowerCheckRequest: current term is [“classname  is Coordinator.java We extracted the following from Elasticsearch source code for those seeking an in-depth context :

synchronized (mutex) {
 ensureTermAtLeast(followerCheckRequest.getSender(); followerCheckRequest.getTerm()); 
 if (getCurrentTerm() != followerCheckRequest.getTerm()) {
 logger.trace("onFollowerCheckRequest: current term is [{}]; rejecting {}"; getCurrentTerm(); followerCheckRequest);
 throw new CoordinationStateRejectedException("onFollowerCheckRequest: current term is ["
 + getCurrentTerm() + "]; rejecting " + followerCheckRequest);
 } 
 // check if node has accepted a state in this term already. If not; this node has never committed a cluster state in this
 // term and therefore never removed the NO_MASTER_BLOCK for this term. This logic ensures that we quickly turn a node
