Siddharth Seth commented on TEZ-1697:
-------------------------------------
bq. Siddharth Seth Isn't this unsafe if we do not compare checksums?
Checksums are definitely a much safer approach. However, also a lot more
expensive. A WARN is being logged. I think the file size check will be
sufficient for most cases, and weird bugs caused as a result of different jars
- there's at least something to look for with the log message in place. I could
enhance the log message to include DEBUG level file name details.
