We are using Cloudera Manager on our cluster and one of the node on the
management console shows "Red" under physical memory.
When I login to the node as admin and do a Top this is what I see.
I don't see any problem. Why is the management console panicking that there
is a memory issue and I don't see it on the server. Is this a bug?
Thanks.
