Tim Armstrong updated IMPALA-4683:
----------------------------------
Issue Type: Improvement (was: Bug)
> Intelligently blacklist scratch disks with physical I/O errors
> --------------------------------------------------------------
>
> Key: IMPALA-4683
> URL: https://issues.apache.org/jira/browse/IMPALA-4683
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 2.3.0, Impala 2.5.0, Impala 2.6.0, Impala 2.7.0,
> Impala 2.8.0
> Reporter: Tim Armstrong
> Priority: Major
> Labels: resource-management
>
> I'm splitting this out from IMPALA-2079 since there are really two different
> parts to that.
> This JIRA is to track process-wide blacklisting of scratch directories on
> disks that exhibit physical I/O errors that may indicate a failing disk.
> We do not necessarily want to permanently blacklist disks, since that can
> result in daemons being in a bad state where they can't allocate any scratch
> space until they are restarted. Instead we should consider time-base
> blacklisting or some kind of administrative support to reenabled blacklisted
> disks.
