Hbase and "ghost regionservers"
Håvard Wahl Kongsgård 2012-08-16, 12:17
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
