I need to check if any index already exist or not or re-start or start up  
the ES Data node.

I am facing issue if I restart the ES Data node and then directly check if  
an index exist or not. I am always getting response as "false" (even if it  
exist and a valid one). But if, I perform a search or any other operation  
on that index and then again check "is index exist" then I am correctly  
getting "true" as response. Could you guide me what I might be missing or  
doing wrong.

I am using the Java client API and using following code snippet for it:-

_1- to start the data node :-_

```
    defaultSettingsFile = new

```

FileInputStream(ElasticSearchConfig.modulesDir + "/" +  
ElasticSearchConfig.ES\_DEFAULT\_PROP);

settingsBuilder.loadFromStream(ElasticSearchConfig.ES\_DEFAULT\_PROP,  
defaultSettingsFile);

```
    // override the default properties
    settingsFile = new FileInputStream(ElasticSearchConfig.modulesDir +

```

"/" + ElasticSearchConfig.ES\_OVERRIDE\_PROP);

settingsBuilder.loadFromStream(ElasticSearchConfig.ES\_OVERRIDE\_PROP,  
settingsFile);

```
    Settings finalSettings = settingsBuilder
            .put(ElasticSearchReservedWords.CLUSTER_NAME.getText(),

```

ElasticSearchConfig.clusterName)  
.put(ElasticSearchReservedWords.NODE\_NAME.getText(),  
ElasticSearchConfig.esDataNodeProperty.getName())  
.put(ElasticSearchReservedWords.NODE\_MASTER.getText(), true)  
.put(ElasticSearchReservedWords.NODE\_DATA.getText(), true)  
.put(ElasticSearchReservedWords.PATH\_DATA.getText(),  
ElasticSearchConfig.esDataNodeProperty.getDataPath())  
.put("discovery.zen.ping.multicast.enabled", false)  
.put("discovery.zen.ping.unicast.hosts",  
ElasticSearchConfig.unicast\_hosts) // //  
NetworkUtils.getLocalAddress().getHostName()  
.put("indices.store.type", "mmapfs")  
.put("index.number\_of\_shards",  
ElasticSearchConfig.numberOfShards)  
.build();

```
    node = nodeBuilder().settings(finalSettings).node();
    node.start();

```

_2- To check if Index exist :-_

```
IndicesExistsRequest request = new IndicesExistsRequest(indexName);
IndicesExistsResponse response =

```

getClientAdminNode().indices().exists(request).actionGet();

Thanks  
Gaurav
