> org.apache.accumulo.core.client.TableNotFoundException: Table (Id=r) does not exist
>  at org.apache.accumulo.core.client.impl.Tables.getTableName(Tables.java:128)
>  at org.apache.accumulo.core.client.impl.ActiveScanImpl.<init>(ActiveScanImpl.java:63)
>  at org.apache.accumulo.core.client.impl.InstanceOperationsImpl.getActiveScans(InstanceOperationsImpl.java:138)

> The table from the previous test was deleted at the end of the test, but, somehow, a tabletserver returned an ActiveScan for that table. When the client tried to unwrap the table ID into a table name, it got a TableNotFoundException.
> Semantically, if a client is asking for active scans on a server, and the server reports a scan for a table the client doesn't think exists, it's reasonable to assume it was just deleted and not return that ActiveScan from the API call.
> Right now, this situation results in an exception back to the client and they get no results.
