> sually we can't ensure lastblock alwaysfull...please let me know purpose of

> long blockSize = trgInode.getPreferredBlockSize();

> final BlockInfo last = trgInode.getLastBlock();
> if(blockSize != last.getNumBytes()) {
> throw new HadoopIllegalArgumentException("The last block in " + target

> + " but file block size = " + blockSize);
> }
> If it is issue, I'll file jira.
