Hi,

I'm running Elasticsearch 1.7.6 and have been successfully changing threadpool settings for bulk threadpools as my cluster scales.

It seems recently I made a typo in Marvel when updating the transient threadpool settings for the bulk and now I am getting this error:

> [node.settings] [es1] failed to refresh settings for [org.elasticsearch.threadpool.ThreadPool$ApplySettings@1bfc389b]  
> org.elasticsearch.common.settings.SettingsException: Failed to get setting group for [threadpool.] setting prefix and setting [threadpool.bulktype] because of a missing '.'

I am performing this update:

> PUT \_cluster/settings  
> {  
> "transient": {  
> "threadpool.bulk.type": "fixed",  
> "threadpool.bulk.size": "8"  
> }  
> }

Any ideas on how to get this issue resolved as nothing I do changes these settings?

Thanks,  
Sam
