Description

The log message from
```
             logInfo(s"Started reading broadcast variable $id with $numBlocks pieces " +
               s"(estimated total size $estimatedTotalSize)")

```
multiples two ints to calculate `estimatedTotalSize` which will overflow when the broadcast exceeds 2Gib.
