Hello Kaven, It's not all necessary to run HM on server running DN. Actually it's not advisable to do so, as HM has high memory requirements and running other daemons on the same machine may lead you to problems. The basic cluster setup, which people normally use looks somewhat like this :
NN+JT(Hadoop master) SNN HM(Hbase master) DN+TT+RS Warm Regards, Tariq https://mtariq.jux.com/ cloudfront.blogspot.com On Sat, Feb 23, 2013 at 12:45 AM, kaveh minooie <ka...@plutoz.com> wrote: > Hi everyone, > > I had a quick question. do I need to be running datanode on the server > that is running hbase master or datanode should be running only on servers > that are running as regionserver? > > thanks, > -- > Kaveh Minooie >
