Andrew Wong reassigned KUDU-2136:
---------------------------------
Assignee: Andrew Wong
> Add a "crashed"/"failed" mode to tablets
> ----------------------------------------
>
> Key: KUDU-2136
> URL: https://issues.apache.org/jira/browse/KUDU-2136
> Project: Kudu
> Issue Type: Improvement
> Reporter: Andrew Wong
> Assignee: Andrew Wong
>
> There are a number of errors that currently crash Kudu tablet servers (e.g.
> disk failure). In the push to keep tablet servers alive in spite of these
> failures, the affected tablets should no longer service any type of request.
> Writes should not proceed, scans should be bounced to another tablet server,
> flushes and compactions should exit early, etc. The tablet should act as
> though it were deleted, with the exception that its data is not yet deleted,
> for the sake of durability in case it is the last remaining replica.
> This mode may be need to be entered from a myriad of tablet operations: from
> corruptions in reading a cfile, from disk failures when flushing to disk
> (while locks may be held), etc.
