This actually seems to be a bigger problem: As no mapping for the fields is
found, the query passed to `deleteByQuery` will have no fields set. This means
that **the entire row is removed even though we just wanted to remove a single
CF** :boom:. I have created a [test
case](https://github.com/gerhardgossen/gora-419) to demonstrate this. The test
case is set up for Gora 0.5, because I couldn't get Nutch working on 0.6 yet.
This code in AccumuloStore did not change between the releases, so it should
still apply. Can anyone else try to reproduce it 0.6?
Is it possible to create a bugfix relase including this patch for 0.5,
because Nutch does not support 0.6 yet (see NUTCH-1946).

> Issue Type: Bug
> Components: gora-accumulo
> Affects Versions: 0.6
> Reporter: Gerhard Gossen
>
> In {{AccumuloStore.put(k, v)}} fields of type MAP or ARRAY are cleared first
> before they are set to the new value. This is done in the methods
> {{putMap}}/{{putArray}} using a call to {{deleteByQuery(q)}}. The name for
> fields to be deleted is taken from the current column. However,
> {{deleteByQuery}} tries to translate the field names of the query to column
> names again, which fails with a log message like
> {code}
