Hi Lars,

Done: https://issues.apache.org/jira/browse/HBASE-4903

What's the best option to solve this?

Thanks,
Daniel

However the only way of modifying it that I could find is through Result.readFields(). That would require the user to create the Result object he wants, serializing it and then deserializing.
