> I came across the blog post
> http://www.3pillarglobal.com/insights/hbase-coprocessors and this interesting
> bit:
> {quote}
> This means that you can load both Observer and Endpoint Coprocessor
> statically using the following Method of HTableDescriptor:
> {noformat}
> addCoprocessor(String className, org.apache.hadoop.fs.Path jarFilePath, int
> priority, Map<String,String> kvs) throws IOException
> {noformat}
> In my case, the above method worked fine for Observer Coprocessor *but didn’t
> work for Endpoint Coprocessor, causing the table to become unavailable and
> finally I had to restart my HBase*. The same Endpoint Coprocessor worked fine
> when loaded statically. Use the above method for Endpoint Coprocessor with
> caution.
> {quote}
> To check this I wrote a test, attached. It passes, all seems ok. Guessing the
> complaint was due to user error, probably jar placement/path issues.
> Let's still commit the test.
