Druid Hot Cold tier setup

I am new to Druid and currently I am trying to setup hot and cold tier setup.
I went through the documentation and got the required configurations for our environment:

4 Historical nodes: Cold tier storage type configuration given in historical properties

1 Historical node: Hot tier storage type configuration given in historical properties

I tried to pushing sample data to realtime node and didnt get it stored in either of historical nodes.

Our data is not more than a TB in deep storage.

Can you please help me the next set of required configurations to enable the pipeline?
