Customize configuration on a specific node
Hi,
Is it possible to customize a node configuration on a specific node?
I installed a 4-nodes cluster. There is 4 HDD on 3 of my nodes and 3 on the
last.
I can't manage to find a way to change the configuration of my node on this
specific node.
I want to change datanode directories and mapreduce directories on that
specific node
Is there a way to do that ?
An other question : Is it possible to remove a service on a node after you
add it ? I can't manage to find a way to do that.
Regards,
Julien Naour

Julien,
I do think it is a useful feature to have.
Yes, it is possible to remove host components with the REST API.
You first put the host component to be deleted in MAINTENANCE state [1].
Once you do that, you can invoke DELETE on that host component resource:
[1]

Hi Yusaku,
Thank you for your quick response.
I think it could be usefull in a dev perspective to add and remove services
from the WebUI. Is it possible from the REST API ?

Hi Julien,
Customizing configs on specific hosts is an experimental feature that you
can try out if you are audacious (not yet production ready) by turning on a
flag in one of the files for the web UI. We will be hardening and
officially releasing this feature in the near future.
You cannot remove a service from a node from the web UI. Do you want to
file a feature request JIRA for that?
