Hi,all
I installed Ambari 1.4.1.25 and HDP 2.0.6，until now I have 6 datanodes and two namendoes,but when I try to expand the cluster,in order to add more datanodes into the cluster,there are the errors reported in ambari-agent logs:

I have already tried to restart the amabri-server and ambari-agent,after the restart,there isn’t any error,but not for a long time,the erros above come out ,and the web shows no heartbeat for the new node,how can I resolve this problem?
