Hello,
You can find a great explanation of HBase file locality in HDFS here
http://www.larsgeorge.com/2010/05/hbase-file-locality-in-hdfs.html .
The short answer is that HBase file locality improves with time since files
are recreated during compactions as close as possible to the RS running
node
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.

Posting this again in plaintext to see if it registers successfully.
Hi,
It appears that the Kerberos authentication integration into HBase is via JAAS
Krb5LoginModule. That is,
I can setup up the Client application context and configure where/how the
client Kerberos principle is

It can, but you want to consider how disk is allocated in the cluster.
A typical and recommended configuration is HBase RegionServer and HDFS
DataNode
I assume a timer may need to be increased based on these messages. Any
thoughts as to which one or is it something else?

I'm sorry I'm losing it.
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
Thanks for the suggestions. I will fix my cluster set up.
