Hi Sun, Thanks for letting us know. Seth ...
Thanks for letting us know.
I have installed nodemanage and regionserver together on the same machines with Ambari1.4.1.
But I found Mapreduce take lots of cpus(often more than 90% cpu usage. Machine has 24 cores and run max 18 YarnChilds concurrent).
So I want to move regionserver to other machines, seperate from nodemanage.
I do not know how to delete regionserver on the original machines.
I note Restful API has DELETE method. Is that useful or could you give me some other suggestion.
