Have you looked at the [snapshot and restore functionality](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/modules-snapshots.html) and the [HDFS snapshot plugin](https://www.elastic.co/guide/en/elasticsearch/plugins/current/repository-hdfs.html)?

Thanks for your response.

Yes we installed **repository-hdfs** plugin in all node in the cluster and restarted.

When we send snapshot request it throwing error response.

Request:

```
     PUT _snapshot/my_hdfs_repository
         {
         "type": "hdfs",
         "settings": {
         "uri": "hdfs://xxxxxxxx:12345/",
         "path": "/dev/test/snapshot",
         "security.principal": "abc@TEST-xyv.COM"
     }
  }

```

Response:

`{ "error" : { "root_cause" : [{ "type" : "repository_exception", "reason" : "[my_hdfs_repository] failed to create repository" } ], "type" : "repository_exception", "reason" : "[my_hdfs_repository] failed to create repository", "caused_by" : { "type" : "unchecked_i_o_exception", "reason" : "Cannot create HDFS repository for uri [hdfs://yyyyyyy:12345/ "caused_by" : { "type" : "i_o_exception", "reason" : "Failed on local exception: java.io.IOException: org.apache.h s : local host is: \"xxxxxxxx.server.net/xx.yyyy.zz.qq\"; destination host is "caused_by" : { "type" : "i_o_exception", "reason" : " **org.apache.hadoop.ipc.RpcException** : RPC response exceeds m "caused_by" : { "type" : "rpc_exception", "reason" : "RPC response exceeds maximum data length" } } } } }, "status" : 500 }`

Please help me to resolve this issue. Thanks in advance.
