Gunther Hagleitner commented on HIVE-11118:
-------------------------------------------
+1. You could use multiple exception handlers instead of the if-then-else. I
also think [~xuefuz] is right, but that probably requires introducing a new
interface that can check magic byte for participating formats, etc. Maybe
create a follow-up jira?
> Load data query should valide file formats with destination tables

> Load data local inpath queries does not do any validation wrt file format. If
> the destination table is ORC and if we try to load files that are not ORC,
> the load will succeed but querying such tables will result in runtime
> exceptions. We can do some simple sanity checks to prevent loading of files
> that does not match the destination table file format.
