      Description

      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.
