Yes, the jar file contains all the required classes.

If you are configuring the coprocessor via
hbase.coprocessor.region.classes, then it is a region endpoint.
For the moment, only table-configured coprocessors support loading
from a jar file in HDFS. Coprocessors configured in hbase-site.xml
need to be resolvable on the regionserver's classpath.
I
I tried to attach the coprocessor directly to a table, and it is able to
load the coprocessor class. Unfortunately, when I try and use the
coprocessor I get a ClassNotFoundException on one of the supporting classes
required by the coprocessor.
It's almost as if the ClassLoader used to load the cop
I'm not sure how to tell if it is a region endpoint or a region server
endpoint.
I have not had to explicitly associate the coprocessor with the table
before (it is loaded via "hbase.coprocessor.region.classes" in
hbase-site.xml), so it might be a region server endpoint. However, the
coprocessor c
Hi Tom,
First off, are you talking about a region endpoint (vs. master
endpoint or region server endpoint)?
As long as you are talking about a region endpoint, the endpoint
coprocessor can be configured as a table coprocessor, the same as a
RegionObserver. You can see an example and description
Are you attempting to add the coprocessor via hbase-site.xml or via the
shell?
If the HBase Shell, check out chapter 13.3.2 in the ref guide[1]. It walks
through loading an example. The given file path is just a URL that gets
handed directly to Hadoop's Path class, so the example you gave would ma
Hi Benjamin,
This is expected behavior. Commons Lang 3 is not backwards compatible with
Commons Lang 2.x. They use different java packages in an effort to ease
projects that have to rely on both while transitioning.

Is it possible to deploy an endpoint coprocessor via HDFS or must I
distribute the jar file to each regionserver individually?
In my testing, it appears the endpoint coprocessors cannot be loaded from
HDFS, though I'm not at all sure I'm doing it right (are delimiters ":" or

By the way, Ted, when I am adding hbase-site.xml to the classpath, I do not

Hi,
I am running from my Eclipse on Windows (using Java 1.6) a simple API call
to Hbase 0.98.5 installed on a remote cluster.
The call
admin = new HBaseAdmin(conf);
passes..
However, the next line
admin.listTables();
is *stuck* forever.
Do you have any hints?!
Best regards
Benjamin
Many thanks!
Strangely, when adding commons-lang 3.2, it failed.
Adding back the 2.6 it worked!

Which release of HBase are you using ?
If 0.98.x, here is the dependency on commons-lang:
2.6
