Anoop Sam John commented on HBASE-12112:
----------------------------------------
As it may change and possibly boolean param not needed in 2.0, I will remove
below from CellUtil
public static Cell createKeyOnlyCell(Cell c, boolean lenAsVal) {
Will handle the creation in Filter class itself as of now.
Also the method and what it is doing is not always matching. CellUtil being
public exposed API, let us not mess it up.
> Avoid KeyValueUtil#ensureKeyValue some more simple cases

> This include fixes with
> - Replace KeyValue#heapSize() with CellUtil#estimatedHeapSizeOf(Cell)
> - Printing the key portion of a cell (rk+cf+q+ts+type). These are in
> Exception messages
> - HFilePrettyPrinter - Avoiding ensureKeyValue() calls and calls to
> cell#getxxx() which involves bytes copying. This is not a hot area still we
> can avoid as much usage of deprecated methods as possible in core code. I
> believe these bytes copying methods are used in many other parts and later we
> can try fixing those as per area importance
> - Creating CellUtil#createKeyOnlyCell and using that in KeyOnlyFilter
