   @RexXiong Please take a look at `CelebornIntegrityCheckSuite`. 
   
   1. I introduced a bit flip in one of the partition location files using 
`ShuffleReaderGetHookForCorruptedData`
   2. Then test for 3 scenarios:
   - Run app without integrity checks - App reads expected number of records, 
app succeeds but data does not match
   - Run app with integrity checks and no stage rerun - As expected app fails 
due to commit metadata mismatch
   - Run app with integrity checks and stage rerun enabled - App succeeds and 
data matches
