milleruntime opened a new issue #111: AssertionError thrown where never should happen
URL: https://github.com/apache/accumulo-testing/issues/111
 
 
   I saw this while running a rwalk on a 5 node cluster.
   ```

   ```
   
   Then looking at where the error is thrown, it seems like this could be bad:
   ```
   public String doBulkFateOperation(List<ByteBuffer> args, String tableName)
         throws AccumuloSecurityException, AccumuloException {
       try {
         return doFateOperation(FateOperation.TABLE_BULK_IMPORT2, args, Collections.emptyMap(),
             tableName);
       } catch (TableExistsException | TableNotFoundException | NamespaceNotFoundException
           | NamespaceExistsException e) {
         // should not happen
         throw new AssertionError(e);
       }
     }
   ```
