> We assume that the size fits to an int:
> https://github.com/apache/impala/blob/308fda110758b0fc58e5b1f477d635aac29aea75/be/src/exec/hdfs-orc-scanner.cc#L253
> If the size overflows, then we can incorrectly hit the following error check
> (this check is meant to avoid crashing due to corrupt metadata). I see no
> other ways this could cause problems, if the catch still succeeds (because
> the overflow led to a valid looking length), then the data will be read
> correctly.
> This looks like a trivial fix, but I am concerned about lack of testing of
> >2GB files
