Some code the support my previous comment: 

{code}
RowGet rowGet = new RowGet(row);
htable.lockRow(rowGet);
row.addColumn("info:");  // overloads for bytes and String
RowResult = htable.getRow(rowGet);
htable.unlockRow(rowGet);
{code}

> The current API does not scale very well. For each new feature, we have to add many methods
to take care of all the overloads. Also, the need to batch row operations (gets, inserts,
deletes) implies that we have to manage some "entities" like we are able to do with BatchUpdate
but not with the other operations. The RowLock should be an attribute of such an entity.
> The scope of this jira is only to replace current API with another feature-compatible
one, other methods will be added in other issues.
