stack commented on HBASE-12297:
-------------------------------
I suppose the Interface forces us create an array here?
+ checksumObject.update(ByteBufferUtils.toBytes(hdr, 0, hdrSize), 0,
hdrSize);
Its going to be slow indexing through each byte of a DBB.
That is good you do the hasArray check first.
> Support DBB usage in Bloom and HFileIndex area
