Hi Team, I am facing issue while running the Orient DB with *DServer.sh (
Distributed Mode in 3 node cluster - Node1, Node2, Node3 )*, mainly the
issue I am facing is related to Orient DB Studio and other Distributed API
commands which gives the updates about Distributed Nodes
Below are the few things to show case, how it is running currently and its
behaviour:
