@Apache9 , thanks for review, yes , for HBASE-27053 , it checksum is removed
from the the `curBlock` ByteBuff in `FSReaderImpl.readBlockDataInternal` once
the checksum is verified, and it create HFileBlock by the `curBlock` ByteBuff
which checksum is removed.
` // remove checksum from buffer now that it's verified
int sizeWithoutChecksum =
curBlock.getInt(Header.ON_DISK_DATA_SIZE_WITH_HEADER_INDEX);
curBlock.limit(sizeWithoutChecksum);
long duration = EnvironmentEdgeManager.currentTime() - startTime;
if (updateMetrics) {
HFile.updateReadLatency(duration, pread);
}
HFileBlock hFileBlock = createFromBuff(curBlock, checksumSupport,
offset,
nextBlockOnDiskSize, fileContext, intoHeap ? HEAP : allocator);`
