Chia-Ping Tsai commented on HBASE-18546:
----------------------------------------

For operational compatibility, we should fix the Increment. But i have no use cases..

> We don't pass the custom timestamp for Increment, and the increment's timestamp always be rewrite. Hence, user can't increment a cell with custom timestamp.

>         for (Cell cell: values) {
>           valueBuilder.clear();
>           valueBuilder.setQualifier(UnsafeByteOperations.unsafeWrap(

>           valueBuilder.setValue(UnsafeByteOperations.unsafeWrap(
>               cell.getValueArray(), cell.getValueOffset(), cell.getValueLength()));

> In contrast to Increment, user can append the cell with custom timestamp. It would be better that make their behavior consistent.
