I recently upgraded my ELK stack from 5.6.1 to 5.6.3 and now logstash can no longer create index in elasticsearch. I have another instance running with 5.6.1 with x-pack and it has no issues. The one running on 5.6.3 does not even have x-pack. I am able to manually create index but when i map .conf to the index it fails to create any entries. I have checked logstash log and elasticsearch log but cannot find any mapping to error except the one which says"[2017-10-11T11:45:32,790][WARN][r.suppressed] path: /\_cat/indices, params: {v=}  
org.elasticsearch.cluster.block.ClusterBlockException: blocked by: [SERVICE\_UNAVAILABLE/1/state not recovered / initialized];"
