Zhihong Yu commented on HBASE-4991:
-----------------------------------
I feel some of the recent proposals / requirements are far more complex than
the one @ 09/Dec/11 16:48
There wasn't such requirement when Mubarak outlined his plan @ 01/Feb/12 07:43,
either.
Of course, having generic framework for all the master-coordinated tasks allows
future additions to be concise. But I think that should have been outlined
clearly in the early stage of development of a feature.
Consider, that few of us know how Accumulo does similar tasks, we should plan /
brainstorm / design carefully so that the generic framework comes up to our
expectations. This would take a month, at least.
e.g. once an action fails, we need to decide whether we should retry or
rollback. For retry, we need a method to specify timeout or the number of
retries. For rollback, another action needs to be associated with the original
action.
Consider, that the refactoring Mubarak has agreed to do is on the common path
of applying the generic framework. I think there is value following the plan
specified @ 01/Feb/12 07:43
Once the generic framework is developed, we can revisit this feature (and
instant schema change). I would anticipate some refinement of the framework in
the process of integration.
@Stack, @Todd: what do you think ?
