Can you put them someplace that I can pull them? I took another look at your logs. I see that a region is missing files. That means it will never open and just keep trying. Grep your logs for FileNotFound. You'll see this: hbase-clmanager-regionserver-ILREDHAT012.log:java.io.FileNotFoundE

Thanks for the logs Slava. I notice that you have not upped the ulimit on your cluster. See the head of your logs where we print out the ulimit. Its 1024. This could be one cause of your grief especially when you seemingly have many regions (>1000). Please try upping it. St.Ack Slava G
