Issues while creating an index after updating from 0.15 to 0.16.1

Elastic Stack Elasticsearch
1

I have an utility method that takes care of deleting and recreating
the index that was working fine with version 0.15.0. Now after
updating to 0.16.1 i get an exception in the last line:

Caused by:
org.elasticsearch.cluster.routing.RoutingValidationException: [Index
[6e737712-8833-4802-b079-698dabf40d19]: Wrong number of shards in
routing table, missing: [5, 6, 7]]

client = new TransportClient().addTransportAddress(new

// Delete any old index with our name
try{

client.prepareDelete().setIndex(indexName).execute().actionGet(TIMEOUT);
} catch (ElasticSearchException ignored) {
System.out.println(ignored)
}

// Prepare new index with settings
Settings settings =
ImmutableSettings.settingsBuilder().put("index.number_of_shards", 8)
.put("index.number_of_replicas", 1).build();

client.admin().indices().prepareUpdateSettings(indexName).setSettings(settings).execute().actionGet(TIMEOUT);

Thanks a lot!

You are updating the index.number_of_shards setting for the index, which causes it to fail. In general, you should not do that, but in 0.16, there is no safeguard for that now...

ok, pushed a check to now allow to change the number of replicas when updating settings (in 0.16 and master branches). This was a change caused by the feature to allow more settings to be changed in runtime using update settings.
