Jerry He commented on HBASE-18573:
----------------------------------
There is no guarantee that initializing it with 1 will do any good. No
assumption can be made on the number of columns that will be added to a family.
> Update Append and Delete to use Mutation#getCellList(family)

> In addxxx() of Put and Increment, Mutation#getCellList(family) is called to
> get cell list from familyMap. But in the other 2 sub-class of Mutation:
> Append and Delete, the logic like Mutation#getCellList(family) is used, like
> {code}
> List<Cell> list = familyMap.get(family);
> if(list == null) {
> list = new ArrayList<>(1);
> }
> {code}
> in
> {code}
> public Delete addColumn(byte [] family, byte [] qualifier, long timestamp)
> {code}
> of Delete
> We could make them to call Mutation#getCellList(family) to get better
> encapsulation
