stack commented on HBASE-5843:
------------------------------

Nicolas, the above should be put on the dev list.  Its great stuff.  Too good to be buried out here as a comment on issue with such an unsexy subject.

>          Issue Type: Umbrella
>    Affects Versions: 0.96.0

> A part of the approach is described here: https://docs.google.com/document/d/1z03xRoZrIJmg7jsWuyKYl6zNournF_7ZHzdi0qz_B4c/edit
> The ideal target is:
> - failure impact client applications only by an added delay to execute a query, whatever the failure.
> - this delay is always inferior to 1 second.
> We're not going to achieve that immediately...
> Priority will be given to the most frequent issues.
> Short term:
> - software crash
> - standard administrative tasks as stop/start of a cluster.
