I think your devrackA-03 zookeeper is not quite "ok" - it doesn't seem
to be part of the quorum.

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
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 hdfs
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.

First, Yep I am a newbie to Hadoop/Hbase. I have read both of the
O'Reilly books (Hadoop and Hbase), so my knowledge level at this point
is pure book learning and understanding the log messages is very vexing.
Second, based on the recommendations of this mail-list I decided to move

the poser by making them aware of the trade offs and why it's a good/bad idea

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
What kind of explanation is this???

Hi Mike,

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.

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 fa

A typical and recommended configuration is HBase RegionServer and HDFS
DataNode colocated on the nodes. The DataNo
Yes.

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.
