Hello, I'm having trouble decommissioning nodes in Hadoop. This worked previously for me in this version of hadoop (0.18.2) and I cannot pinpoint what is wrong. I am adding the host I wish to decommission to the exclude file specified in site.xml. I then run refreshNodes on the master. Rather than the "Decommission in progress" that I'm used to seeing, it instead lists the node both in Live datanodes and Dead Datanodes.
When I go to the DFS health webpage, the only difference I see is when I mouseover the node in Live nodes, it appears as IP:PORT in the tooltip popup. When I mouseover the version of it that appears as dead, it lists as HOSTNAME:PORT. These are both the same node, just listed twice. The port is the same between both mouseovers. Does anyone know what I am doing wrong? I checked slaves, and that node is only listed once. It's also listed in exclude only once. At no point do I have IP addresses listed. Thanks for any suggestions.
