Subject Re: Quick Links Disabled

I am using 1.5.1 at the moment, I have also used 1.6.0 and as you say the

I think the problem lies in the fact that we have active-active NameNodes
with replication between them, Ambari is probably getting confused as a
result. From the screenshot as you can see we only display one of the
active NameNodes, the other two are alive and well but Ambari is unaware of

If I could make Ambari just link to the primary NameNode that would
probably suffice for now. I'm going to look into the proper solution as we

Thanks very much!
