----------------------------------------
bq. Large entries aren't the only problem - large indices can be real bad too.
good point. I will add a comment to 1459
> Track tablet migrations and failed loads
> ----------------------------------------
>
> Key: ACCUMULO-1453
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1453
> Project: Accumulo
> Issue Type: Improvement
> Components: master, tserver
> Affects Versions: 1.5.0, 1.4.3
> Reporter: Mike Drob
>
> If a bad RFile or Tablet somehow gets in the system and brings down a
> tserver, then as the master migrates it to other servers it will likely cause
> cascading failures.
> It might be a good idea to keep track of how many consecutive failures to
> load there are for a given tablet, and either warn or refuse to host the
> tablet if this value exceeds a given threshold.
