shardulm94 opened a new pull request #1957:
URL: https://github.com/apache/iceberg/pull/1957
Make it easier to find out exactly which file was being read when we
encountered an error either opening the task or when reading rows from the task
Heres an example of how it looks now
```
Exception: Error reading file: hdfs://namenode/table/path/part-r-00001.orc
