Is it possible to specify different thresholds for different nodes in  
the cluster? I could not find it in the documentation, when updating  
the setting through the cluster settings as described on  
[http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules-allocation.html#disk](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules-allocation.html#disk)  
the threshold is applied to every node.

When specifing the thresholds through the configuration file, will it  
then be only applied to the node reading the configuration? In this  
case how to I prevent the cluster settings being applied and  
overwriting the configuration file (remove a setting).

Thanks for any thoughts,  
Michel

It's a cluster level setting, so all nodes use the same one.  
As far as I know, there is no node level setting.

What if I set the option in the configuration file, will it then only  
be applied to the node reading the configuration file?

The link you provided is for transient settings, meaning they will reset  
once the cluster restarts. Doing this via the configurations file ensures  
the settings are loaded back.

As Mark said, this is cluster level settings. If you have nodes with  
different HD characteristics you probably want to use percentages for the  
watermark values.

If I hava multiple data dirs on a node, can I apply these settings to each  
directory individually?

Nope, it's for the node as a whole.
