How do you test an HBase Endpoint Coprocessor?

[#1]

How can you test to see if the processor is working?

Is there a way to test from the shell?

[#2]

Can you describe the function of the coprocessor ?

It should be possible to use shell and observe the side effect your coprocessor makes.

[#3 · Accepted solution]

You can add debug logs in your coprocessor.

Enable DEBUG logging on region servers and check the logs after action is performed in shell.

I am just trying on the Sum processor example that's out there for now

[#5]

Here is a good example of observer coprocessor with testing code. Don't know if we have anything to test through hbase shell.

it's the example on for Sum
