--------------------------------
bq. That seems pretty long and should be improved.
Yep, the default was set for new users that won't understand the impact. You
should change it if you care about mttr.
bq. That seems can simplify the process. What do you think?
It's important to have the feature in the core, if not the feature is not
tested hence does not work, or does not work for long. There is a jira to
support a standard administration tool in the core (I can't find it, but it
exists for sure).
> Improve HBase MTTR - Mean Time To Recover
> -----------------------------------------
>
> 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.
