> Avoid KeyValueUtil#ensureKeyValue some more simple cases
> --------------------------------------------------------

> Key: HBASE-12112
> URL: https://issues.apache.org/jira/browse/HBASE-12112
> Project: HBase
> Issue Type: Sub-task
> Components: regionserver
> Reporter: Anoop Sam John
> Assignee: Lars Hofhansl
> Fix For: 2.0.0, 0.99.1
>
> Attachments: HBASE-12112.patch
>
>
> 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
