> Key: ACCUMULO-1248
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1248
> Project: Accumulo
> Issue Type: Sub-task
> Affects Versions: 1.4.0
> Reporter: Keith Turner
> Fix For: 1.5.0
>
>
> When a tablet has multiple locations, the client side code that caches tablet location from the metadata table will currently just take one of the locations.
> If a tablet has multiple locations, then the client code should fail. Proceeding when a tablet has multiple location clould result in silent data loss or reading stale and/or incomplete data.
