Tribe node configuration


I'm trying to setup a tribe node to talk to the two cluster I have. Here is the elasticsearh.yml

---------------------------------- Cluster -----------------------------------

Use a descriptive name for your cluster: tribe ----what should this be?

------------------------------------ Node ------------------------------------

Use a descriptive name for the node: node1
node.master: false false

#------------------------------------- Tribe ---------------------------------------

t1: X ["X1", "X2", "X3"] false
t2: Y ["Y1", "Y2", "Y3"] false

This configuration doesn't work. I get service unavailable in the kibana screen.
The documentation doesn't talk about all the configurations in the elasticsearch.yml

Any help would be appreciated!
