i am using 6 node cluster in ambari where HDP is 2.3 and ambari 2.6
it was running fine till ast 2 days but some how system got shutdown and since then not able to start the services.
It always says
Call From hostname/IPaddress to hostname:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
i am able to do SSH from master to data nodes and vice versa as well
Selinux is OFF on all Nodes
Firewall is OFF on all Nodes
Cat /etc/hosts is configured properly and getting FQDN while running hostname -f
not sure where its not allowing connection
Getting below error from each node and even from master node (same node)
