HDP 2.4 Cluster Failure

HDP 2.4 Cluster Failure

New Contributor

I want to know why does my 2 node HDP 2.4 cluster which I deployed several times using ambari gets Failed.

I don't have access to the ambari UI since it hungs up saying "Loading....." forever.

I have copied the log files of ambari-server and ambari-agent from master node and slave node and attached to the ticket.


Please let me know why I am not able to deploy the cluster.
