> In ByteBufferIOEngine , we have the assert:
> {code}
> @Override
> public void write(ByteBuffer srcBuffer, long offset) throws IOException {
> assert srcBuffer.hasArray();
> bufferArray.putMultiple(offset, srcBuffer.remaining(), srcBuffer.array(),
> srcBuffer.arrayOffset());
> }
> @Override
> public void write(ByteBuff srcBuffer, long offset) throws IOException {
> // When caching block into BucketCache there will be single buffer
> backing for this HFileBlock.
> // This will work for now. But from the DFS itself if we get DBB then
> this may not hold true.
> assert srcBuffer.hasArray();
> bufferArray.putMultiple(offset, srcBuffer.remaining(), srcBuffer.array(),
> srcBuffer.arrayOffset());
> }
> {code}
> Should remove the assert, and allow to write off-heap ByteBuff to bufferArray.
