  Resolution: Fixed
Hadoop Flags: Reviewed
  Status: Resolved  (was: Patch Available)

Pushed to master. Will update the release notes shortly.
Thanks for the patient reviews and nice feedbacks [~anoop.hbase] and 
[~saint@gmail.com].
The javac warnings should be due to the Unsafe method additions.

 In L2 cache (offheap) an HFile block might have been cached into multiple 
 chunks of buffers. If HFileBlock need single BB, we will end up in recreation 
 of bigger BB and copying. Instead we can make HFileBlock to serve data from 
 an array of BBs.

ramkrishna.s.vasudevan updated HBASE-12213:

Release Note: 
The read path from the Hfileblock is now backed by a new data structure 
represented by an abstract class ByteBuff. The name is similar to nio 
ByteBuffer.
The new ByteBuff class has various APIs to read and write primitives to the 
underlying implementation similar to how nio ByteBuffer provides.
We have 2 implementations of the ByteBuff now - a single ByteBuffer backed 
implementation (SingleByteBuff) and a multiple ByteBuffer backed implementation 
(MultiByteBuff).
The single byte buffer (SingleByteBuff) backed implementation will be used for 
the HFileBlocks that come from HDFS and from LRU cachce.
The blocks that gets created out of BucketCache will be of type MultiByteBuff 
and the read operations are performed over this data structure which 
intelligently moves across different Byte buffers that it is formed of.

Updated patch fixing the checkstyle and javadoc.  Also removes the 
ByteBuff.copy() API - the static one and move that to as abstract method 
put(offset, src, srcOffset, srcLength) in the Bytebuff as per Anoop's 
suggestion.

Corrected the javadoc warning. Also changed the asSubBuffer API that was 
returning a Pair to accept a Pair as an arg and use the same Pair to set the BB 
and offset instead of creating it every time.  As per the comments in RB.

 In L2 cache (offheap) an HFile block might have been cached into multiple 
 chunks of buffers. If HFileBlock need single BB, we will end up in recreation 
 of bigger BB and copying. Instead we can make HFileBlock to serve data from 
 an array of BBs.

Attachment: HBASE-12213_9_withBBI.patch

Corrected the test case. It was assert failure that happens only in test cases. 
 Corrected the checkstyle and javadoc.  May be some new ones may be due to 
UnsafeAccess. Renamed SingleByteBuffer to SingleByteBuff and MultiByteBuffer to 
MultiByteBuff.

Uses MBB in the read path.  
- Since HBASE-12295 is not there we cannot allow the Bucket Cache to use the 
actual MBB based Blocks without doing copy. For now we have copied the 
Bucketcache and created an MBB out of it.
- the HFileReader uses MBB and the relative reads have been replaced with 
absolute position based reads.  
The absolute position based reads uses the UnsafeAccess APIs. So better to make 
use of them. Tried to do a small micro benchmark mimicing the logic in 
blockSeek with and without positional reads using MBB.
- There are some TODOs that will get changed after BufferBackedCells come in 
to place.  
- PrefixTree, blooms need to be handled to work with MBB that are offheap.  
That can be done later.

 In L2 cache (offheap) an HFile block might have been cached into multiple 
 chunks of buffers. If HFileBlock need single BB, we will end up in recreation 
 of bigger BB and copying. Instead we can make HFileBlock to serve data from 
 an array of BBs.
