>
> For reducing disk IO, one block is separated to multiple parts, BlockScanner
> scans only one part per round. Expect that after several rounds, the full
> block should be scanned
> Add a new option "dfs.block.scanner.part.size". the maximum data size per
> scan by the block scanner. this value should be the multiple of chunk size,
> for example, 512, 1024, 4096 ...
> Default value is -1, will disable partial scan.
