For the record, this issue was caused by multiple entries in /etc/hosts for global IP.
for example /etc/hosts 127.0.0.1 localhost ntnu.no 176.19.190.1 master 176.19.190.1 removing the second entry (master 176.19.190.1), resolved the issue. -Håvard On Thu, Aug 16, 2012 at 2:17 PM, Håvard Wahl Kongsgård <[email protected]> wrote: > Hi, when I start my hbase cluster, hbase sometimes list 'ghost > regionservers' without any regions > > kongs2.medisin.ntnu.no:60020 1345115409411 > requests=0, regions=0, usedHeap=0, maxHeap=0 > > netstat does not list any services on 60020 > > if I start a region server locally > > I get one real services and the ghost server > > kongs2.medisin.ntnu.no:60020 1345119112497 > requests=0, regions=64, usedHeap=141, maxHeap=1487 > kongs2.medisin.ntnu.no:60020 1345119112497 > requests=0, regions=0, usedHeap=0, maxHeap=0 > > Is it possible to manually blacklist or remove regionserver, via the > hbase shell? > > I use the latest hbase from cloudera > > -Håvard -- Håvard Wahl Kongsgård Faculty of Medicine & Department of Mathematical Sciences NTNU http://havard.security-review.net/
