Dynamically update Number of nodes used by Hive's LLAP

[#1]

Hello,

I use a cloud solution of hadoop (HDInsight) with Interactive Query HDI 3.6

I try to manage dynamic scale up and scale down of the cluster. I can change dynamically the number of worker node but when I do this, I have to change manually the number of nodes used by Hive's LLAP in Ambari UI : see screen shot

I want to do this dynamically with a script. I don't find how to do it without Ambari. is it possible?

Thank you.

I found the answer: we can use Ambari API or edit configuration by script as explained here https://cwiki.apache.org/confluence/display/AMBARI/Modify+configurations#space-menu-link-content
