How to restore the notebook from S3?

[Shuya Tsukamoto]

Hi!

I am using zeppelin 0.5.6 with Amazon EMR (emr-4.7.2).

I was tried section "Notebook Storage in S3".
I use the configuration such as the following because my case is EMR.

      "Configurations":[
         {
            "Classification": "export",
            "Properties":{
               "AWS_ACCESS_KEY_ID": "mykeyid",
               "AWS_SECRET_ACCESS_KEY": "myaccesskey",
               "ZEPPELIN_NOTEBOOK_S3_USER": "hadoop",
               "ZEPPELIN_NOTEBOOK_S3_BUCKET": "mybucket",
               "ZEPPELIN_NOTEBOOK_STORAGE": "org.apache.zeppelin.notebook.
repo.S3NotebookRepo"
            },
            "Configurations": []
         }
      ]
   }
]
```


I was able to save the notebook to S3. But I couldn't restore the notebook
from S3.
I want to restore the notebook automatically from S3 when I re-create the
EMR cluster.

Could you please help me?
Thank you.
