How can I get fsimage with curl command?

[#1]

I can get fsimage with 

hdfs dfsadmin -fetchImage ./fetched_image

This command seems to get fsimage from the below url.

https://{namenode-1}:9470/imagetransfer?getimage=1&txid=latest

I have multiple namenodes, but dfsadmin fetches only from the first namenode.

So, I want to fetch with curl command, inserting a certain namenode address into {namenode}.

How can I achieve this?

Just running 

curl https://{namenode-1}:9470/imagetransfer?getimage=1&txid=latest

prints error even though kerberos ticket is the same as dfsadmin:

<p>Problem accessing /imagetransfer. Reason:
<pre> Authentication required</pre></p>
