Review Comment:
   failed index will have it's own log when index is added to failedIndexs 
list, right?  In this case, I would prefer to complete remove following if you 
are ok.
   
   ```
                 Set<Integer> failedIndexes = sis.getFailedIndexes();
                 if (!failedIndexes.isEmpty()) {
                   // There was a problem reading some of the block indexes, 
but we
                   // did not get an exception as there must have been spare 
indexes
                   // to try and recover from. Therefore we should log out the 
block
                   // group details in the same way as for the exception case 
below.
                   logBlockGroupDetails(blockLocationInfo, repConfig,
                       blockDataGroup);
                 }
   ```
