I guess I did my trick to get the zookeeper_namespace . I wrote a small piece of code to connect zookeeper and get the childrens from zookeeper then match with hive server with port number . Ex : 

from the below output , I have 2 namespace for hive , but my server match with the 1st one. That I need 🙂

{:req_id=>3,
:rc=>0,
:children=>
["serverUri=lnxcdh23.testme.org:10000;version=1.1.0-cdh5.4.4;sequence=0000000001"],

{:req_id=>2,
:rc=>0,
:children=>[],

Thanks,
