    hey guys, let's just push it forward, and deal with it later on. IMO the changes proposed
by  @gerhardgossen make sense and I am happy he took the time to nail it down :) Thanks @gerhardgossen
!

> 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}

   : Mapping not found for field: mtdt
> {code}
> As a result, the query is not restricted to any field and the *entire row is deleted*.
