--------------------------------------
Summary: 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
Reporter: Anoop Sam John
Assignee: Anoop Sam John
Fix For: 2.0.0, 0.99.1
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
