Hello Asha, as far as I understand the configuration you posted is for the front-end node which connects to the master via ClusterClient. So front-end node and master are not in the same cluster. What do you use the journal for in the front-end then?
What persistence settings do you use on master? I am asking this, because it seems that you are running ClusterSharding on master and it also needs persistence to be set up.
