-----------------------------------
Resolution: Fixed
> Scanner retry time does not back off or include jitter
> ------------------------------------------------------
>
> Key: ACCUMULO-3683
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3683
> Project: Accumulo
> Issue Type: Improvement
> Components: client
> Reporter: Eric Newton
> Assignee: Eric Newton
> Fix For: 1.7.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When a tablet server goes down, scans will begin failing. The
> {{ThriftScanner}} has a hardcoded 100ms pause between retries.
> There are two things that would improve this: an exponential back-off, and
> some jitter, so the tservers aren't hammering the metadata table with
> requests for the new location at the same time the master is trying to
> re-assign the tablets.
