Thanks for the follow up. I was going to suggest that exact thing for command-line, but the part I wasn't clear on was how to get Eclipse to load the HBase jars both during compile time AND runtime. I'm not super familiar with IDE-based development, but that is the key to getting HBase applications to run.
Glad you resolved it!

Oh ok, thanks for clarifying. Yes, you can most certainly develop and test apps in Ecplise. In fact, there is a blog post and video tutorial on that exact process posted in this thread. I bet that'll get you the help you need, but please let us know if not.
Regards.

If this is a Cloudera Manager cluster and you're using parcels, the lib directory you're looking for will be in /opt/cloudera/parcels/CDH/lib

Try placing the following on the command line before your "hadoop jar...." command:
HADOOP_CLASSPATH=`hbase classpath`
Which brings up a good point, you ARE running your program with the syntax "hadoop jar /path/to/your/jar className..." right?

I think what you're describing is what we refer to as a "Gateway" machine. On a cluster under Cloudera Manager's control, we allow you to add the "Gateway" role to a machine outside the cluster. This installs the base CDH packages and deploys client configurations to that machine so that it can run regular hadoop commands like you describe and can upload files and run jobs against the cluster.
It sounds like your database server is already able to do this, can you clarify the question?

@crigano I'm dropping your previous message into this thread, as well as @busbey 's since they both seem to have gotten derailed into an offline email thread. and FWIW, there is no Joey on this thread, not sure if there is some threads getting crossed here or what.
From busbey:
Hi Chris!
If you're not already familiar with Netbeans, I'd recommend sticking with the development tools you're comfortable with.
You should check your notification settings; I know I responded to at least one of your other and I believe someone else responded to another.
-Sean
from crigano:
put the in the IDE: mvn -Dhadoop.profile=2.0 package
Now I get completion in the IDE will not include classes from these dependencies or their transitive dependencies (unless they are among the open projects).
Please download the dependencies, or install them manually, if not available remotely.
The artifacts are:
org.apache.hadoop:hadoop-core:jar:2.0.0-cdh4.3.0
What do you recommend Joey,
thanks,
Chris

Great suggestion, Gerd. I see what you mean and we'll bounce this idea around. Our support department internally categorizes security as a facet of each component, because you can have security-related topics for any particular component of the hadoop ecosystem. I'll let you know our feedback soon, though.
Regards,
Clint
