Org.elasticsearch.cluster.block.ClusterBlockException: blocked by: [SERVICE_UNAVAILABLE/1/state not recovered / initialized];

Hi Everyone,

I am getting below exception in ES when I am trying to querying the data from ES.

My Java code :-

String localhostname = java.net.InetAddress.getLocalHost().getHostName();
ImmutableSettings.Builder settings = ImmutableSettings.settingsBuilder();
settings.put("cluster.name", "pstcluster");
settings.put("node.name", localhostname + "-eslocalnode");
settings.put("node.master", false);
settings.put("node.data", false);
settings.put("node.max_local_storage_nodes", 1);
settings.put("http.enabled", false);
settings.put("discovery.zen.ping.multicast.enabled", false);
settings.putArray("discovery.zen.ping.unicast.hosts", "172.16.9.19:9300");

node =nodeBuilder().clusterName(clusterName).client(true).settings(settings1).node();
node.start();
client = node.client();
