Tianying Chang updated HBASE-5843:
----------------------------------
@ nkeywal What is the application bug(AB) mentioned in your design doc? Do you
mean hbase bug? or hbase client application code bug?
If it is hbase client application code bug, does that need stop/start region
server to fix the issue?
If it is hbase code bug, do you refer to hbase bug that cause region server
einter some bad state like deadlock, and so on? I think that could benefit from
restarting region server to fix the problem.

> Key: HBASE-5843
> URL: https://issues.apache.org/jira/browse/HBASE-5843
> Project: HBase
> Issue Type: Umbrella
> Affects Versions: 0.96.0
> Reporter: nkeywal
> Assignee: nkeywal
>
> 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.
