I am using ES 1.1.1 and Hadoop hortonworks 2.2.2 and have installed the  
plugin '_repository-hdfs'  
([https://github.com/elasticsearch/elasticsearch-hadoop/tree/master/repository-hdfs](https://github.com/elasticsearch/elasticsearch-hadoop/tree/master/repository-hdfs)  
 [https://github.com/elasticsearch/elasticsearch-hadoop/tree/master/repository-hdfs](https://github.com/elasticsearch/elasticsearch-hadoop/tree/master/repository-hdfs))_ in  
ES. I have created one custom plugin action which invokes snapshot and  
restore and set hadoop related jars to ES\_CLASSPATH

The handleRequest(...) of the custom plugin action looks as below :  
public void handleRequest(final RestRequest request,  
final RestChannel channel) {  
LocalFileSystem fs = FileSystem.getLocal(new Configuration());  
Path path = new Path("backup");  
fs.delete(path, true);

```
PutRepositoryResponse putRepositoryResponse = 

```

client.admin().cluster().preparePutRepository("test-backup").setType("hdfs").  
.setSettings(ImmutableSettings.settingsBuilder().put("path", path)).get();

```
CreateSnapshotResponse createSnapshotResponse = 

```

client.admin().cluster().prepareCreateSnapshot("test-backup",  
"test-snap").setWaitForCompletion(true).setIndices("test").get();

client.admin().cluster().prepareGetSnapshots("test-backup").setSnapshots("test-snap").get().getSnapshots().get(0).state();

```
RestoreSnapshotResponse restoreSnapshotResponse = 
 client.admin().cluster().prepareRestoreSnapshot("test-backup", 

```

"test-snap").setIndices("test").setWaitForCompletion(true).execute().actionGet();

```
XContentBuilder builder = restContentBuilder(request);

```

builder.value("successfully done - " +  
putRepositoryResponse.isAcknowledged() +":"+  
createSnapshotResponse.getSnapshotInfo().status().getStatus()+  
":"+restoreSnapshotResponse.getRestoreInfo().status().getStatus());  
channel  
.sendResponse(new XContentRestResponse(request, OK, builder));  
}

After the first invocation, I get this error  
{"error":"UncategorizedExecutionException[Failed execution]; nested:  
IOException[Filesystem closed]; ","status":500}
