Hi Mike,
Running RS on a machine where DN isn't running?
I am not following here. Andy said that both are on the same node. Where in
this thread did someone imply something else? Just curious.
Cheers,
Lars

Well...
I wasn't sure if St.Ack was displeased by my comments on Andrew's response, or
my references to KISS where the second S is stupid, reference to 'dead hookers'
or reference to drugs.
I was just covering my bases. :-)
With respect to Andrew's response, I saw something that I wasn't sure

First, thank you.
I moved my HRegionservers not my HQuorumPeers.
I have checked the network and everyone can talk to everyone. I can
even talk to my HQuorumPeers via nc from the nodes that should be
running my HMaster on it and my HRegionservers.

Ok - thanks for checking connectivity.
I presume you already have doublechecked the hbase-site.xml in your
region server that points to the zookeeper and hdfs-site.xml pointed
to the namenode.
I once got a similar error when HBase was picking up a stray
core-site.xml / hdfs-site.xml from the
When I do locate hbase-site.xml, locate hdfs-site.xml, and locate
core-site.xml there are 2 locations for each on the HRegionServers.
All files are either in $HADOOP_HOME/conf or $HBASE_HOME/conf and there
are files of the same name in example directories.
I moved my HRegionServers back to my

Can a regionserver and quorumpeer reside on the same node?
Not necessarily...Both are totally different processes..In a Hadoop
cluster typically HBase Master and a ZooKeeper quorum peer run on a
machine and regionservers are spread across the cluster. But this
totally depends on you.

It can, but you want to consider how disk is allocated in the cluster.
A typical and recommended configuration is HBase RegionServer and HDFS

Running RS on a machine where DN isn't running?
So then the RS can't store its regions locally. Not sure if that would ever be
a good idea or recommended.
Thought the initial question is running ZK on the same node as a RS which isn't
a good idea and a recipe for
