Are you using secure HBase? Don't -- it'll only get in the way for a simple
example. Is the master running? Be sure to run ./bin/start-hbase.sh from
the directory where you unpacked the tgz. You can omit the conf.set(...)
business from your code. By default, the configuration will point to local

Glad to hear you're making progress. Can you provide more information about
your environment? Are you running a released version of HBase or from a
checkout of trunk? How did you install HBase -- or are you running from the

I suggest you use a Maven project.
I can copy-paste a small pom.xml for you to get you started.
It will solve all of those missing JARS you have.
Just make sure to install M2Eclipse plugin (Eclipse Marketplace)

I'm able to duplicate the problems I've described by using only the first
two lines of code.
Entire class is:

Nick: Thanks still again for the lengthy comments.
This is a quick reply covering some of the points.
There have been no Class not found exceptions in the more recent versions
of my system setup.
jps -l immediately after starting hbase, shows:

Wow.
That security exception encountered was harmless and a red herring
unfortunately (HBase security is not enabled unless you take several steps
not done here), and assumptions from that point have made this quite
unsatisfactory for everyone. I wish you well with your explorations of
Cassandra.
I really don't understand what you are saying.
From the beginning I stated that I was very much a beginner.
I valued all the advice I got.
I felt humble in the presence of you true experts.
So to interpret my actions as lacking humility is confusing.
What in the world did I do wrong that I could
Many more assumptions. The *only* thing I said is you should try
approaching an unfamiliar system with a bit more humility. I doubt Nick
wouldn't be interested in helping you further. It might be helpful, rather
than argue what you or your son might think, to ask Nick et al for
clarification or

Do you have a local zookeeper running? Telnet localhost 2181 connect to
anything?
Obviously we run 0.94 with no security setup with no problem. Hence looking for
basic setup problems.

I'm trying to run a test that extends HBaseTestingUtils.
It worked fine with the old versions when it extended HBaseClusterTestCase.
Since it is deprecated (also same for HBaseTestCase) I adjusted the test a

Hi all,
I'm upgrading our cluster with the following versions:

Hadoop 0.20.3 to 1.0.3

I still don't understand if it is optional to use the security or not ?
if i'll set the following in hbase-site.xml:

I'm trying to run a test for HBase (some think we wrote, internal) on my
laptop - runs perfectly with the old versions of Hadoop, HBase and
ZooKeeeper.
After deploying the new versions and re-compiling our code, I run the test.
When I try to instantiate new HBaseAdmin(getConfiguration()) -
Security is optional.
If you don't set any SASL protected ACLs on znodes, then the client doesn't
need to authenticate, you should not add any security options to the site file
like you currently are, and the message on startup about the state of JAAS
configuration is informative only and is
Server null usually means you haven't configured hbase.zookeeper.quorum in your
client's hbase-site.xml file. And that is usually because you are using a
Configuration not created by HBaseConfiguration.create()
If so the JAAS warning is a red herring.
On May 31, 2012, at 8:52 PM, Amit Sela
I mean of course server null means that hbase.zookeeper.quorum config property
is unset. And the two most common reasons are:
1. Not defined in the site file
2. Configuration object not created with HBaseConfiguration.create()
I hope this is clearer.
On May 31, 2012, at 8:59 PM, Andrew
I did some debug and the code does calls HBaseConfiguration.create() -
since my test extends HBaseTestingUtility.
and conf.properties.get(hbase.zookeeper.quorum) returns localhost.
Is that properly set, or should it be something else ? keep in my it's a
test running on my laptop, so it seems OK
Great, now remove any security related Zookeeper properties that you added in
hbase-site.xml. Only keep hbase.zookeeper.quorum.
