Elasticsearch Migration Plugin installation steps

[Deb]

Cross-posting from stackoverflow

In order to upgrade 2.3.z elasticsearch to 5.x, I have successfully installed elasticsearch migration plugin, but when linking to http://localhost:9200/_plugin/elasticsearch-migration/ I get a blank page.

Can someone let me know the following:-

1. Do I have to install the plugin all the machines in the cluster?
2. Do I have to restart all the machines in the cluster?

I have already tried the steps as mentioned here. But still I am getting a blank page.

I'd follow the instructions here as the first option - https://github.com/elastic/elasticsearch-migration/tree/2.x

[Deb]

Yes Mark that is what I have referred.

Did you restart the node as well?
It shouldn't need to be installed on all nodes, just the one you are trying to access via the browser.

[Deb]

No I did not restart the node. Let me try and check.

Restarting is not needed.

@Deb do you have CORS enabled on your node?

elastic/elasticsearch-migration

[Deb]

@val No. I think as per the doc cors is needed if I am trying to access a remote cluster. But I am trying in localhost.

Can you open your browser's developer tools? What do you see in the Network tab?

[Deb]

No cors is needed for local query and restart is also not needed for any of the nodes. It was a permission issue. Working now.

Thanks for all your help.
