Log Context

Log “index [” + index + “] has no active shard copy”classname  is We extracted the following from Elasticsearch source code for those seeking an in-depth context :

for (String index : indices) {
 final GroupShardsIterator shardIts = clusterService.operationRouting()
 .searchShards(clusterState; new String[] { index }; null; null; null; null);
 final IndexSelector indexResult = new IndexSelector(shardIts);
 if (indexResult.nodeToShards.isEmpty()) {
 onIndexFailure.accept(index; new NoShardAvailableActionException(null; "index [" + index + "] has no active shard copy"));
 } else {
 this.indexSelectors.put(index; indexResult);
