Node is down, but still i am able to connect to Database from it.

I am having a weird problem with Vertica 3-node cluster setup. Only one node comes up while creating database. Following is the status of the nodes: [dbadmin@ip-10-0-2-185 ~]$ admintools -t list_allnodes Node | Host | State | Version | DB ---------------------+------------+-------+-----------------+---------- v_mpp_test_node0001 | 10.0.2.184 | UP | vertica-7.2.3.0 | MPP_TEST v_mpp_test_node0002 | 10.0.2.185 | DOWN | vertica-7.2.3.0 | MPP_TEST v_mpp_test_node0003 | 10.0.2.186 | DOWN | vertica-7.2.3.0 | MPP_TEST But still i am able to connect to the database from that node. Query Database too.

I even killed the vertica process on one of the nodes that is down, still i was able to connect to the database from that node using admintools. I am unable to understand what is happening here. Is this some issue with how the servers are setup?
