Eric Payne commented on HADOOP-11012:
-------------------------------------
[~jira.shegalov], thank you for reviewing this patch.
bq. Now you read the "magic" twice however. I woud change the original code
just by enclosing the switch statement into try-catch-EOF.
Would it be sufficient to do as [~jlowe] suggests and save the magic bytes and
switch on that?
