will result in an error result
## What changes were proposed in this pull request?
In the `checkIndexAndDataFile`,the `blocks` is the ` Int` type, when it is
greater than 2^28, `blocks*8` will overflow, and this will result in an error
result.
In fact, `blocks` is actually the number of partitions.
