Although right now WALObserver is the only RS level CP, but it'd better not to indicate here. I changed the parameter name to "rsCoprocessors" and added a javadoc @param note; what do you think? Could also just call it "coprocessors" as you suggested. bq.

I think we should use the whole class name for the comparator. bq. bq. Andrew Purtell wrote: bq. Full classnames are canonical and avoid accidental conflict, but are unwieldy and not so nice to look at. Judgement call, I'd say. I think it unlikely that for any given deployment two coprocessors will have the same class name but be in a different package. I would agree with Andrew and use getSimpleName(). bq.

Removed HMasterInterface.java changes at Andy's recommendation: now no difference with trunk. bq.

It's odd to put the new test cases to this file. Maybe TestClassLoading is a better place. Good idea; moved to a new source file: TestCoprocessorReporting.java. bq.

Thanks; removed extra string and added comment with your point. - Eugene ----------------------------------------------------------- This is an automatically generated e-mail.
