      Description

      We've hit a couple of recent bugs where scanners crashed on data that was corrupted in relatively minor or predictable ways: IMPALA-3441, IMPALA-3745, IMPALA-3646

      These could have all been reproduced with a truncated file or a single byte being changed.

      We should do some randomised testing of HDFS scanners with simple errors like that, in order to find such bugs more proactively.
