> The ActionChange.getChangeKey() simply concatenates together the row key, family, and qualifier which could lead to incorrect conflicting keys. For example (rowKey='a', family='bc') would conflict with (rowKey='ab', family='c'). A simple fix would be to prefix each part with the byte length of each part.
