Sorry. Haven't gotten to this, yet.
Scanning in HBase being about 3x slower than straight HDFS is in the right
ballpark, though. It has to a bit more work.
Generally, HBase is great at honing in to a subset (some 10-100m rows) of the
data. Raw scan performance is not (yet) a strength of HBase.
Yes that's a great post it helped me appreciate the complexity of the whole
thing to. There's gotta be a JIRA in here somewhere :)

I do want to know. Maybe that'll get my problem resolved.

I believe the only discussions have been on avoiding talk about coprocessor
reloading, as it implies either a reimplementation of or taking on an OSGi
runtime
If you truly want to understand the weirdness behind what you witnessed,
then make a big cup of coffee, prepare a notebook with a pen and sit down

I can. I'll change /etc/sysconfig/network to localhost, for a hostname.
In CentOS/Fedora/Red Hat, /etc/hostname does not exist and it's
/etc/sysconfig/network :) .

Good on you Wouter. HappyBase makes me... well...
If you want to add happybase to
http://wiki.apache.org/hadoop/SupportingProjects, make yourself an id on
the hadoop/hbase wiki and send it to me offlist and I'll enable you as an
editor.
Thanks boss,

Hi all,
I have just released HappyBase 0.5. This release adds support for a
thread-safe connection pool, and some other minor fixes and
enhancements.

+1 for a VM on your own machine. That's how I do it because its easy to
control and muck with network settings .
Cant you just Edit etc/hostname file ?

Hostname is "ysg.connect". I'm ok with not using it in distributed mode,
for now.
This is my ifconfig info:
$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:1A:92:46:8C:66
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
This is a machine identity problem. HBase simply uses the normal Java
APIs and asks "who am I?". The answer it gets is
ip72-215-225-9.at.at.cox.net. Changing this should only be a matter of
DNS configs, starting with /etc/hosts. What is your machine's hostname
exactly (run "hostname")? When you pin
The thing that gets me, really gets me, is that the only thing inside of
/etc/hosts is this:
127.0.0.1localhost
Also, I did a search for host.name and could not find it in any html files
(which I presume is the documentation).

That seems to be the case. The thing that I don't get is if I missed any
"global" setting in order to make everything turn towards localhost. What
am I missing?
I'll scour the HBase docs again.

Here is what I don't get. Why doesn't _everything_ go through
localhost? Is there a way to force this? Would I need to hack
up some HBase code in order to force this?

It says your event_data table isn't assigned anywhere on the cluster.

Ah yeah the master advertised itself as:
Attempting connect to Master server at
ip72-215-225-9.at.at.cox.net,46122,1369408257140
So the region server cannot find it since that's the public address
and nothing's reachable through that. Now you really need to fix your
networking :)

Ok, weird, it still seems to be looking towards Cox.
Here is my hbase-site.xml file:

Ok, that's done. Now, when I go to either 127.0.0.1:60010 I get that
a connection was reset or do "list" in the shell, it all just hangs for a
while and I don't see a response, until I get a very long Java exception.

Hi Tariq/Jyothi,
Sorry to trouble you again.
I think this problem is solved but i am not able to figure out why in
client's /etc/hosts file , i need to put an entry of zookeeper's location.I
have configured everything as IP addresss in Hbase server so why this
/etc/hosts comes in picture as i under
Can someone please help here ?

Thanks Damien.
I add core-site.xml and hdfs-site.xml link under HBase conf dir, then
everything works well.
please ingore this thread. sorry.

And about the visibility of HDFS conf in HBase classpath, so ?

Hello,
Is hdfs-site.xml and core-site.xml available in HBase java process
CLASSPATH ?
Did you add
```
dfs.client.failover.proxy.provider.test-cluster
org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider
```
In hdfs-site.xml ?

Hi,
I configured HDFS ha using QJM, so I configured hbase as following:
hbase.rootdir
hdfs://test-cluster
test-cluster is my name sevice ID in my HDFS configuration,
but HBase cannot start, Exception:
java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative

Hi,
I am again facing this issue.
This time around its on different machine where i am configuring hbase in
pseudo distributed mode.
Client ( Java program ) connects to zookeeper fine as seen in below
zookeeper logs :-
