@renato2099: you need to distinguish between the *field name* (e.g.
'content') that is used in the external API (for example as members of the
value objects) and the *column name* (e.g. 'f:cnt') that is used in the data
store (in this case Accumulo). The mapping between both is specified in the
`gora-*-mapping.xml` files.
`deleteByQuery` is part of the external API and therefore receives field
name values (as part of the query parameter). If we change this method it would
break user code that tries to delete a map/array field. As a map is represented
in Accumulo as a collection of fields, we would also need to delete `cf:*`
instead of a single `cf:qualifier`.
> putMap and putArray use column instead of field name to deleteByQuery

> Project: Apache Gora
> 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}
