> When reading from an Orc file, SchemaEvolution evolution tries to determine
> if this is an Acid compliant format by comparing field names with Acid event
> names in {{SchemaEvolution.checkAcidSchema}}. Would be good to make this
> comparison case insensitive.
> This requirement comes in from HIVE-20699 where a Hive query is being used to
> run compaction (and hence write the compacted data to the bucket files via a
> HiveQL query). Since hive converts all column names to lower case, the
> compacted files end up with lower case Acid schema columns. The change is
> much simpler when made in Orc.
