> 2015-10-09 14:59:40 WARN  DFSClient:1150 - fetchBlockByteRange(). Got a checksum exception for /tmp/file0.05355529331575182 at BP-353681639-10.10.10.10-1437493596883:blk_1075692769_9244882:0 from DatanodeInfoWithStorage[10.10.10.10]:5001
> All 3 replicas cause this exception and the read fails entirely with:
> BlockMissingException: Could not obtain block: BP-353681639-10.10.10.10-1437493596883:blk_1075692769_9244882 file=/tmp/file0.05355529331575182
> Code to reproduce is attached.
> Does not happen in 2.7.0.
> Data is read correctly if checksum verification is disabled.
> More generally, the failure happens when reading from the last block of a file and the last block has <= 512 bytes.
